MSBSHSE Syllabus for Class 12 Chemistry

Syllabus at a Glance: 16 Chapters, 70 + 30 Marks

The Class 12 Chemistry syllabus prescribed by the state board has 16 chapters in the textbook. Your final score of 100 marks is built from two separate exams: a theory paper of 70 marks and a practical exam of 30 marks. Both are compulsory. A student who scores 65 in theory but neglects the journal and viva loses marks that are usually easy to earn, so treat the 30 practical marks as seriously as the 70 theory marks.

The syllabus is the same for English medium and Marathi medium students. Only the language of the textbook and question paper changes; the chapters, subtopics and marks weightage do not. So a Marathi medium student can safely use the same chapter list, the same weightage table and the same study plan given on this page.

Always download the syllabus PDF from the official board website rather than a coaching institute's copy. On the cover page, check the session year printed there (for example, 2025-26). A PDF from an older session may still list topics that were later removed, or miss newly added ones [verify].

This page walks you through the full chapter list split into Physical, Inorganic, Organic and Applied Chemistry, the marks distribution between theory and practical, indicative chapter-wise weightage, the practical exam pattern, and a week-by-week study plan. Wherever you need to practise, use the Class 12 Chemistry textbook solutions for all chapters alongside your reading, and solve Maharashtra Board Class 12 Chemistry previous year question papers once a chapter is revised.

Theory and Practical Marks Distribution

Your Chemistry score of 100 is not one exam but two. The theory paper carries 70 marks and is written at the end of the year. The practical exam carries 30 marks and is conducted separately, usually before or alongside the theory paper. Both are compulsory, and you must pass each one. If you fail the practical, the theory marks alone cannot save your result.

The 30 practical marks are not given for one experiment alone. They are split across several heads, and each head rewards a different habit. The usual split is shown below, but confirm the exact breakup with your teacher because the board can change it [verify].

A common mistake is treating the journal as paperwork to be filled the night before submission. Examiners open the journal during the viva and ask questions from it. If your readings look copied or a page is unsigned, you lose marks in two heads at once. The fix is simple: write up each experiment on the same day you perform it, get it signed, and keep the calculations in your own hand.

Internal assessment is the part most students forget until the last month. It may be a small project, a written report, or an evaluation of your completed practical book, depending on what your school follows [verify]. Ask your teacher in the first term what exactly will be assessed, and finish it early. For experiment write-ups and viva preparation, the Class 12 Chemistry practical book solutions and experiment guide covers the standard experiments step by step.

Chapter-wise Weightage (Indicative)

Not every chapter earns the same marks. The board does not print an official weightage table in the syllabus PDF, but the paper pattern and the marks carried by each unit are broadly stable from year to year. The table below groups the 16 chapters by branch and shows the approximate marks each group usually contributes to the 70-mark theory paper. Treat these numbers as a planning guide, not a guarantee, and confirm the current split against the latest board circular for your session [verify].

Within these groups, a few chapters do most of the heavy lifting. Solutions, Electrochemistry, Chemical Thermodynamics and Halogen Derivatives consistently carry more questions than the rest [verify]. A typical paper might give you a numerical on colligative properties, a cell potential calculation, a thermodynamics problem and a reaction-mechanism question from halogen derivatives, all in the same sitting. If you are short on time, these four deserve your first attention.

Weightage drifts slightly each year as the board rebalances question papers, so a chapter marked low one year can gain a question the next. Do not skip a low-weightage chapter entirely, because a single 3-mark question from it is often the difference between 65 and 68. A practical rule: give high-weightage chapters roughly double the revision time of low-weightage ones, but keep every chapter in your final round of revision. To see how these marks actually appear in real papers, work through the Maharashtra Board Class 12 Chemistry previous year question papers and tally chapter-wise marks yourself.

Physical Chemistry Chapters

Physical chemistry is the numerical engine of the paper. Roughly a third of your theory marks sit here [verify], and the questions are the kind you can score full marks on once the formula and the unit conversion are right. The six chapters below move from structure of solids to the speed of reactions, so study them in textbook order the first time and in any order during revision.

Chapter 1: Solid State

This chapter explains how particles are packed in a crystal and what that packing does to properties like density and conductivity. It is mostly conceptual, with a few formula-based questions on unit cell dimensions and packing efficiency.

• Types of solids: crystalline and amorphous, and the forces that hold them
• Unit cell parameters, number of atoms per unit cell, and relationship between edge length and radius
• Packing efficiency of simple cubic, body-centred and face-centred arrangements
• Density of a unit cell and calculations using it
• Point defects: Schottky and Frenkel, and their effect on density
• Electrical and magnetic properties of solids

Typical questions ask you to find the number of atoms per unit cell from a given structure, or to calculate density from edge length and molar mass. A common mistake is forgetting to convert picometres to centimetres before substituting into the density formula. Fix it by writing the conversion factor at the top of your rough work every time.

Chapter 2: Solutions

Solutions is the most numerical chapter in the book. It deals with how solutes change the properties of a solvent, and with concentrations expressed in different ways.

• Types of solutions and expressing concentration: molarity, molality, mole fraction, mass percentage
• Solubility of gases in liquids and Henry's law
• Raoult's law and ideal versus non-ideal solutions
• Colligative properties: relative lowering of vapour pressure, elevation of boiling point, depression of freezing point, osmotic pressure
• Molar mass determination from colligative properties
• Abnormal molar mass and van't Hoff factor

A standard exam question gives you the mass of solute and solvent, then asks for boiling point elevation or molar mass. Marks are usually split between the formula, the substitution and the final answer with units, so show every step. The common error is mixing molarity and molality; remember that molality uses kilograms of solvent and does not change with temperature.

Chapter 3: Ionic Equilibria

This chapter covers equilibrium in solutions of weak acids, weak bases and salts. It is conceptual but carries a fair number of small numericals on pH and solubility product.

• Acids and bases: Arrhenius, Bronsted-Lowry and Lewis definitions
• Dissociation constants of weak acids and bases, and degree of dissociation
• pH and pOH calculations, including buffer solutions
• Hydrolysis of salts and nature of the resulting solution
• Solubility product and common ion effect
• Buffer action and the Henderson equation

Questions often ask you to calculate the pH of a buffer or decide whether a precipitate will form from given ion concentrations. The frequent mistake is using concentration instead of activity or ignoring the dilution step; read whether the volumes are being mixed before you substitute.

Chapter 4: Chemical Thermodynamics

Thermodynamics links heat, work and spontaneity. It is mixed: derivations and definitions sit alongside numericals on enthalpy, entropy and Gibbs energy.

• System and surroundings, state functions and path functions
• First law of thermodynamics and work done in different processes
• Enthalpy, Hess's law and enthalpy of reaction, formation and combustion
• Entropy and the second law
• Gibbs energy and spontaneity, relation between ΔG, ΔH and ΔS
• Third law of thermodynamics

Expect a numerical on ΔG at a given temperature, or a Hess's law problem where you add given equations. Sign conventions cause most lost marks: work done on the system is positive, work done by the system is negative. Write the sign convention once at the start of your answer.

Chapter 5: Electrochemistry

Electrochemistry connects chemical reactions to electricity. It is numerical-heavy and also asks for definitions and cell diagrams.

• Galvanic and electrolytic cells, and writing cell reactions
• Standard electrode potential and the electrochemical series
• Nernst equation and cell potential calculations
• Relation between Gibbs energy and cell potential
• Conductance, molar conductivity and Kohlrausch's law
• Faraday's laws of electrolysis and corrosion

A typical question gives two half-cells and asks for the EMF, or gives a concentration and asks for the cell potential using the Nernst equation. Marks are awarded for the correct cell notation, the balanced reaction and the final value. The usual slip is reversing the sign of the anode potential; remember that for a cell, EMF equals cathode potential minus anode potential.

Chapter 6: Chemical Kinetics

Kinetics studies how fast reactions go and what controls that speed. It is numerical-heavy with a few conceptual questions on order and mechanism.

• Rate of reaction and rate law
• Order and molecularity of a reaction
• Integrated rate equations for zero and first order reactions
• Half-life and its relation to rate constant
• Temperature dependence and the Arrhenius equation
• Collision theory and effect of catalyst

Questions usually ask you to find the rate constant from concentration-time data, or the half-life of a first-order reaction. Graph-based questions are common: identify the order from the slope of a plot. The common mistake is treating a first-order rate constant as a concentration-dependent quantity; k is constant at a given temperature, only the rate changes with concentration.

Once these six chapters are solid, move to the organic chapters, which reward a different kind of practice. If a numerical keeps going wrong, work through the Class 12 Chemistry textbook solutions for all chapters and then attempt the same type from the Maharashtra Board Class 12 Chemistry previous year question papers under timed conditions.

Inorganic Chemistry Chapters

Inorganic chemistry in Class 12 is the part of the paper you can prepare with a highlighter, a notebook and honest repetition. There are few calculations here. What the examiner wants is accurate facts: correct electronic configurations, correct oxidation states, correct colours, correct shapes, and correct reasons for trends. Three chapters carry this load, and together they usually account for a steady share of the theory paper [verify].

Treat these chapters as a memory project with structure, not as reading. Every fact you learn should be attached to a pattern (why the trend exists) or to a comparison table (how it differs from its neighbour). Facts learnt that way survive exam pressure; facts learnt as isolated lines do not.

Chapter 7: Elements of Groups 16, 17 and 18

This chapter walks through three p-block groups: the chalcogens (Group 16: O, S, Se, Te, Po), the halogens (Group 17: F, Cl, Br, I, At) and the noble gases (Group 18). The focus is on how properties change as you go down a group and how they differ across a period, and then on the compounds and uses that follow from those properties.

• Electronic configurations and general trends in atomic and ionic radii, ionisation enthalpy and electronegativity
• Anomalous behaviour of oxygen and fluorine, and the reasons behind it
• Oxidation states shown by each group and the stability of those states
• Preparation, structure and properties of important compounds: oxides of sulphur, oxoacids of sulphur and chlorine, and interhalogen compounds
• Noble gases: occurrence, compounds of xenon, and hybridisation and shapes of xenon fluorides and oxides
• Uses of these elements and their compounds in industry and daily life

A typical question asks you to compare the acidic strength of oxoacids of chlorine, or to explain why fluorine shows only the -1 oxidation state while chlorine shows several. Marks are given for the trend, the reason, and the example, in that order. The common mistake is writing a trend without the reason. Fix it by always adding "because" to your answer.

Chapter 8: Transition and Inner Transition Elements

This chapter moves to the d-block and f-block. The central idea is that partially filled d orbitals give these elements their special character: variable oxidation states, colour, catalytic activity, magnetic behaviour and the tendency to form complexes and alloys. The lanthanoids and actinoids are studied mainly through lanthanoid contraction and comparison.

• Position in the periodic table, electronic configuration and the reason for irregularities in it
• General properties: metallic character, oxidation states, colour of ions, magnetic properties and catalytic behaviour
• Formation of interstitial compounds and alloys
• Lanthanoid series: configuration, lanthanoid contraction and its consequences
• Actinoid series and a comparison with lanthanoids
• Important compounds and applications, including potassium dichromate and potassium permanganate [verify]

Exam questions here are usually short-answer: write the configuration of a given ion, explain why a particular ion is coloured, or state two consequences of lanthanoid contraction. The common error is writing configurations with the wrong number of d electrons for ions, since electrons are removed from the outermost s orbital first. Practise ten configurations in a row until the rule becomes automatic.

Chapter 9: Coordination Compounds

A coordination compound contains a central metal ion bonded to ligands (ions or molecules that donate an electron pair). This chapter explains their nomenclature, structure, bonding and importance in biology and industry.

• Terms: ligand, coordination number, coordination sphere, denticity and chelation
• IUPAC nomenclature of coordination compounds and writing their formulas
• Werner's theory of coordination compounds and its postulates
• Valence bond theory: hybridisation, geometry and magnetic behaviour of complexes
• Crystal field theory: splitting of d orbitals in octahedral and tetrahedral fields [verify]
• Isomerism in complexes, and applications in medicine, metallurgy and analysis

A standard question gives you a complex such as [Co(NH3)6]3+ and asks for its IUPAC name, hybridisation and magnetic nature. Marks are split across these parts, so answer each one separately rather than mixing them into one sentence. The common mistake is confusing the oxidation state of the metal with the charge on the complex; work out the metal's oxidation state first, then use it for the magnetic and hybridisation steps.

Build three master tables: one for group trends, one for oxidation states and configurations, and one for complexes. Add a mnemonic for the electrochemical series and for the order of ligands in the spectrochemical series. Revise these tables aloud, then test yourself by covering the right-hand column. When a chapter feels memorised, move to the Class 12 Chemistry textbook solutions for all chapters and answer the exercise questions without looking at the table. If you want to see how these chapters were actually asked, solve the inorganic portion of the Maharashtra Board Class 12 Chemistry previous year question papers.

Organic Chemistry Chapters

Organic chemistry is the part of the paper where marks are lost quietly. Students often know the reaction but write it without the condition, or draw the product without balancing the equation, and lose half the marks. The five organic chapters in Class 12 build one skill: seeing a functional group and predicting what it will do next. A functional group is the atom or group of atoms that decides a molecule's reactions, for example -OH in alcohols, -CHO in aldehydes, -NH2 in amines and -X in halogen derivatives.

Almost every organic question is a functional group interconversion, meaning a reaction that changes one group into another. Ethanol to ethanal, ethanal to ethanoic acid, ethanoic acid to ethanamide: each step has a reagent, a condition and a mechanism. Learn all three together, never the product alone.

Chapter 10: Halogen Derivatives

This chapter covers compounds in which a halogen atom is attached to an alkyl or aryl carbon. It sets up the substitution and elimination reactions that repeat throughout organic chemistry.

• Classification as alkyl, allyl, vinyl, aryl and benzyl halides, and nomenclature
• Preparation from alcohols, alkanes and alkenes
• Nucleophilic substitution: SN1 and SN2 mechanisms, and which substrate follows which path
• Elimination reactions and the Saytzeff rule
• Reactions with metals, including Grignard reagent formation, and uses of halogen derivatives

A typical question gives 2-bromobutane and asks for the product with alcoholic KOH and with aqueous KOH. The first gives elimination (but-2-ene as the major product), the second gives substitution (butan-2-ol). Marks come for naming the major product and stating the rule or mechanism. The common mistake is writing the minor product as the answer; the fix is to check whether the reagent is alcoholic or aqueous before you start.

Chapter 11: Alcohols, Phenols and Ethers

Here you compare three oxygen-containing families. Alcohols and phenols both have -OH, but the -OH in phenol sits on a benzene ring, which changes its acidity and reactions sharply. Ethers have oxygen between two carbon groups and behave differently again.

• Classification and nomenclature of alcohols, phenols and ethers
• Preparation methods for each family, including industrial routes
• Acidity of alcohols and phenols, and why phenol is more acidic
• Reactions: dehydration, oxidation, esterification, and electrophilic substitution in phenol
• Williamson synthesis for ethers, and uses of each family

Exam questions often ask you to arrange alcohols or phenols in order of boiling point or acidity and give reasons. Write the order, then one line of reason for each position. A distinguishing test question (Lucas test, Victor Meyer test, neutral ferric chloride for phenol) needs the reagent, the observation and the conclusion, all three.

Chapter 12: Aldehydes, Ketones and Carboxylic Acids

This is the longest and most question-heavy organic chapter. It links the carbonyl group (-CHO and >C=O) to the carboxyl group (-COOH) through oxidation and reduction.

• Nomenclature and structure of the carbonyl group
• Preparation of aldehydes and ketones, and of carboxylic acids
• Nucleophilic addition reactions and their mechanism
• Named reactions: Aldol condensation, Cannizzaro reaction, Clemmensen reduction, Wolff-Kishner reduction, Tollens and Fehling tests [verify]
• Acidity of carboxylic acids and the effect of substituents
• Distinguishing tests between aldehydes and ketones

A standard question asks you to distinguish between propanal and propanone using two tests. Write Tollens test (silver mirror with propanal, no reaction with propanone) and Fehling test (red precipitate with propanal). Each test needs reagent, observation and inference for full marks. The common mistake is writing the observation without naming the compound it identifies. The fix: finish every test sentence with "hence the compound is…".

Chapter 13: Amines

Amines are organic derivatives of ammonia, classified as primary, secondary or tertiary by how many carbon groups are attached to nitrogen. The chapter covers their preparation, basicity and reactions, including diazonium salts.

• Classification, nomenclature and structure of amines
• Preparation: reduction of nitro compounds and nitriles, Hofmann bromamide degradation [verify]
• Basicity of amines and its variation in aqueous solution
• Reactions with acids, alkyl halides and acid chlorides
• Diazonium salts: preparation, reactions and synthetic use
• Carbylamine test and Hinsberg test for distinguishing amines

Questions on basicity order are common. Write the order, then explain it using the availability of the lone pair on nitrogen and the effect of solvation. The common mistake is giving the gas-phase order where the aqueous order is asked; read the question carefully.

Chapter 14: Biomolecules

This chapter applies organic chemistry to living systems: carbohydrates, proteins, enzymes, vitamins and nucleic acids. It is mostly factual and quick to revise.

• Classification of carbohydrates: monosaccharides, oligosaccharides and polysaccharides
• Structure of glucose and fructose, and reactions of glucose
• Amino acids, peptide bonds and structure of proteins
• Enzymes, their action and characteristics
• Vitamins: classification and deficiency diseases
• Nucleic acids: DNA and RNA, and their structure

Most questions here are definition and example based: classify a sugar, name the linkage in a protein, or state the deficiency disease for a vitamin. Keep a one-page chart of definitions and examples and revise it weekly.

For organic chemistry, practise writing mechanisms by hand rather than reading them. Then test yourself with the Class 12 Chemistry textbook solutions for all chapters and solve the organic section of the Maharashtra Board Class 12 Chemistry previous year question papers under timed conditions.

Applied Chemistry Chapters

The last two chapters carry the least numerical load and the most definition-based marks. They are short, they appear in the paper every year, and they reward students who keep a clean list of examples. If you are running short of time near the exam, these are the chapters you can finish in two sittings and still score well.

Chapter 15: Introduction to Polymer Chemistry

A polymer is a large molecule formed by joining many small repeating units called monomers. The chapter asks you to classify polymers, describe how they are made, and connect their properties to everyday uses.

• Classification by source (natural, semi-synthetic, synthetic), by structure (linear, branched, cross-linked) and by behaviour on heating (thermoplastic and thermosetting)
• Types of polymerisation: addition and condensation, with one equation for each
• Preparation of common polymers such as polythene, PVC, nylon 6,6, bakelite and terylene [verify]
• Molecular mass, degree of polymerisation and the idea of average molecular mass
• Biodegradable polymers and polymer uses in daily life

A typical question gives you a polymer structure and asks whether it is an addition or condensation polymer, and whether it will soften on heating. Marks come for the classification plus the reason: addition polymers come from monomers with double bonds, and cross-linked thermosetting polymers do not soften because their chains are joined by strong covalent bonds. The common mistake is writing "bakelite is thermoplastic" because it is a familiar plastic. The fix: learn the thermoplastic and thermosetting lists as two separate columns.

Chapter 16: Green Chemistry and Nanochemistry

Green chemistry is the design of chemical processes that reduce or remove the use and generation of harmful substances. Nanochemistry deals with particles in the size range of roughly 1 to 100 nanometres, where the surface area becomes so large that properties change.

• The twelve principles of green chemistry, especially atom economy, use of safer solvents and design for energy efficiency [verify]
• Green solutions such as the use of supercritical carbon dioxide as a solvent and the replacement of hazardous routes in industry
• Nanoparticles, their large surface area to volume ratio, and how this changes reactivity
• Methods of nanoparticle synthesis and applications in medicine, catalysis and materials

Questions here are almost always short answer: state two principles of green chemistry, or give two applications of nanoparticles. Write the definition in one line, then the examples. Diagrams are simple, such as a flow chart of a green synthesis route or a labelled nanoparticle, so practise drawing them neatly. Two chapters, roughly a handful of marks, and very little calculation. Keep a single page of definitions and examples for both, and revise it alongside the Class 12 Chemistry textbook solutions for all chapters so the definitions match the wording your textbook uses.

Practical Exam: Experiments, Journal and Viva

The practical paper is worth 30 marks and is held separately from the theory exam, usually before it. You are given a set of experiments to perform, a journal to submit, and a short viva to face. Each part carries its own marks, so a weak performance in one does not have to sink the whole paper.

The experiments you will be examined on fall into four groups [verify]:

• Volumetric analysis: titrating a solution of unknown concentration against a standard, for example finding the molarity of a potassium permanganate solution using oxalic acid. You must record burette readings, calculate the molarity and write the balanced equation.
• Salt analysis: identifying the cation and anion in a given salt through dry tests, flame tests and confirmatory wet tests. You are expected to write the observations and the inference for each test, not just the final name of the salt.
• Physical chemistry experiments: measuring a physical quantity such as the freezing point depression, viscosity, or pH of a solution, and using the reading to calculate a result.
• Organic qualitative analysis: detecting the functional group in an organic compound using tests such as the sodium bicarbonate test, Tollens' test or the iodoform test.

The 30 marks are split across experiment performance, the journal, the viva and, in many schools, a project or the internal assessment [verify]. Because the exact split is set by the board for each session, confirm the current pattern with your teacher or the official circular.

Keep your journal neat and complete from the start of the year. Write the aim, apparatus, procedure, observations and calculation for every experiment as you do it, and get the journal certified by your teacher well before the exam. An uncertified or incomplete journal costs easy marks that no amount of last-minute study can recover.

Viva questions are based on the experiments you performed and on general chemistry concepts from the syllabus. Expect to be asked why you add a particular indicator, what the end point means, or how you would identify a given ion. Revise the theory behind each experiment using the Class 12 Chemistry textbook solutions for all chapters and the Class 12 Chemistry practical book solutions and experiment guide so your answers match the textbook wording.

Deleted or Retained Topics: What Changed This Year

The state board reviews the Class 12 Chemistry syllabus from time to time, and when it does, it issues a circular that names the subtopics removed from the current session's exam and the ones that stay. "Deleted" means the topic will not be examined that year; "retained" means it stays in the paper. Treat any list you see on a coaching handout or a social media post as unconfirmed until you have matched it against the circular for your session [verify].

Two things go wrong when students skip this check. First, they study a deleted topic in detail and lose hours they could have spent on Electrochemistry numericals. Second, and worse, they assume a topic is deleted because a senior told them so, and then a question from it appears in the paper. The fix is simple: open the latest syllabus PDF on the board website, compare it line by line with the contents page of your textbook, and note every mismatch.

Your textbook edition matters here. If you are using an older print, some chapters may be arranged differently from the current syllabus. Ask your teacher for a one-page summary of what was removed and what was added this year, and keep it pasted inside your journal. Before revision, cross-check that summary against the official circular yourself. Once your chapter list is confirmed, move on to the Class 12 Chemistry textbook solutions for all chapters and solve the previous year question papers, which show you how retained topics are actually asked.

How to Use the Syllabus for Study Planning

Before you plan anything, sort the sixteen chapters into three buckets. Mark a chapter numerical-heavy if most of its marks come from solving problems: Solutions, Electrochemistry, Chemical Kinetics and Chemical Thermodynamics. Mark a chapter theory-heavy if it asks you to recall facts, trends or structures: Solid State, the three inorganic chapters, and Biomolecules. Everything else is mixed, meaning the paper will carry both a definition or mechanism question and a small calculation or equation. This sorting matters because numerical and theory chapters need different study habits. Numericals improve only with daily practice on paper, while theory chapters improve with spaced revision and tables.

A sensible revision order follows that sorting and the weightage you noted earlier. Start with the high-weightage numerical chapters, because they take the longest to become reliable and they reward early practice. Then move to organic chemistry, where mechanisms and named reactions need repeated writing. Inorganic comes next, since it is largely memory work and benefits from being revised closer to the exam when recall is fresher. Leave the two applied chapters, Polymer Chemistry and Green Chemistry and Nanochemistry, for the end. They are short, definition-based and quick to consolidate.

Time allocation should follow weightage multiplied by difficulty, not weightage alone. A four-mark chapter that you find easy needs less time than a four-mark chapter full of numericals. One workable method: give each chapter a difficulty rating from 1 to 3, multiply it by its approximate marks, and use that score to decide how many study slots it gets in a week. Recalculate the score after every test, because a chapter you have mastered should not keep the same slot.

Build a weekly timetable that touches every chapter at least once before the board exam. A practical pattern is to keep one numerical chapter as the daily main block, add one theory chapter for revision, and reserve one slot for organic mechanism writing. Keep Sunday for a mixed set drawn from the chapters covered that week. Write the timetable on paper and tick off slots; an untracked plan is only a wish.

For self-assessment, use a full sample paper or a previous year paper under timed conditions, then mark it strictly against the scheme. For each wrong answer, note the chapter and the reason: a formula you did not recall, a mechanism step you wrote in the wrong order, or a fact you never learned. Fix the reason, not just the answer. Our Class 12 Chemistry textbook solutions for all chapters help you check worked numericals step by step, and the Maharashtra Board Class 12 Chemistry previous year question papers show you the pattern of repeated questions. A common mistake is solving a numerical correctly but skipping the unit or the significant figures; the fix is to write the unit at every step, because examiners award marks for the final answer with its unit, not for the working alone [verify].

Syllabus Overlap with MHT-CET and NEET

A large part of what you study for the board exam is also tested in MHT-CET and NEET. Both entrance exams draw their Chemistry questions mainly from the Class 11 and Class 12 syllabus, so preparing a chapter well for the board usually means you are preparing it for the entrance exams too. The reverse is not always true, which is why the board paper comes first.

These chapters carry heavy weight in all three exams and deserve a thorough first pass:

• Solutions: concentration terms, Raoult's law, colligative properties and molar mass calculations.
• Electrochemistry: Nernst equation, conductance, Kohlrausch's law and electrolysis products.
• Chemical Kinetics: rate laws, order of reaction, half-life and Arrhenius equation.
• Organic chapters: Halogen Derivatives, Alcohols, Phenols and Ethers, Aldehydes, Ketones and Carboxylic Acids, and Amines, especially named reactions and distinguishing tests.
• Coordination Compounds: nomenclature, isomerism, Werner's theory and crystal field splitting.

Prepare these chapters to board depth first, because entrance exams reward speed on the same concepts. A common mistake is studying a chapter only at MCQ level and then losing marks in the board paper's mechanism and derivation questions. The fix is to write full answers once, then practise MCQs for speed.

Some topics are exam-specific. NEET and MHT-CET may skip certain board subtopics, and the entrance syllabi include a few topics your board textbook treats briefly [verify]. Check the latest entrance syllabus before you drop anything.

Official PDF and Marathi Medium Availability

The syllabus you should follow is the one published on the state board's official website. Download the Chemistry PDF for the current session from the board's syllabus page [verify], and open the first page before you read anything else. The cover page carries the session year (for example, 2024-25 or 2025-26) and the subject code. If the year on the PDF does not match your exam year, you have opened an old file. Delete it and download again.

The same syllabus is published in English and Marathi. The chapter numbers, subtopics and marks weightage are identical in both files, so Marathi medium students do not need to study anything extra or skip anything. Choose the language you are comfortable reading, or download both if your textbook is in Marathi but you plan to attempt the paper in English.

To download: open the board website, go to the syllabus or curriculum section, select Higher Secondary Certificate (HSC), then Class 12, then Chemistry. Save the PDF to your phone or laptop so you can check it offline while making your timetable. Avoid syllabus lists on coaching blogs, Telegram groups or note-sharing apps. These are often copied from an older year and may still show topics the board has removed [verify].

Once you have the correct file, compare its chapter list with your textbook's contents page. If a subtopic appears in the PDF but not in your book, ask your teacher whether your edition is outdated. For practice after the syllabus is settled, move on to the Class 12 Chemistry textbook solutions for all chapters and the Maharashtra Board Class 12 Chemistry previous year question papers.

Frequently Asked Questions

How many chapters are there in the Maharashtra Board Class 12 Chemistry syllabus?

The Class 12 Chemistry textbook has 16 chapters. These are grouped into Physical, Inorganic, Organic and Applied Chemistry. The theory paper of 70 marks is set from these 16 chapters, so plan your revision chapter by chapter rather than by section. Check the chapter list printed in your textbook's index to confirm nothing has changed for your session [verify].

What is the marks distribution between theory and practical in HSC Chemistry?

Your total is 100 marks: 70 for theory and 30 for practical. The theory paper is written at the end of the year; the practical exam is held separately, usually before or alongside it. Both are compulsory and you must pass each. The 30 practical marks come from the experiment, journal and viva, so do not leave them for the last week.

Where can I download the official MSBSHSE Class 12 Chemistry syllabus PDF?

Download it from the official state board website, not from a coaching institute's copy. On the cover page, check the session year printed there, for example 2025-26 [verify]. An older PDF may still list topics that were later removed or miss newly added ones. Keep that official PDF as your reference while studying and cross-check it against your textbook index.

Is the Class 12 Chemistry syllabus the same for Marathi and English medium students?

Yes. Only the language of the textbook and question paper changes. The 16 chapters, subtopics and marks weightage are identical for both mediums. A Marathi medium student can use the same chapter list, weightage table and study plan. What differs is the wording of questions, so practise reading technical terms in both languages where you are comfortable.

Which chapters carry the highest weightage in the HSC Chemistry paper?

The board's weightage table gives an indicative mark range per chapter, not a fixed number of questions [verify]. Chapters with more subtopics, such as Solutions, Electrochemistry, Chemical Thermodynamics and Coordination Compounds, usually get more marks. Use the official weightage table to decide how much time each chapter deserves, and confirm the current table for your session [verify].

Have any chapters been removed from the Class 12 Chemistry syllabus this year?

Chapter deletions are decided by the board and printed in the official syllabus PDF for that session [verify]. Do not rely on a senior's old notes or a coaching handout. Open the current PDF, compare its chapter list with your textbook index, and note any deleted topics. If your textbook is older, ask your teacher to confirm which portions are excluded [verify].
