Chemistry is widely considered the fastest-scoring section in JEE Main — a large share of it is direct recall from NCERT rather than heavy problem-solving. It splits into three distinct branches, each needing a different study approach.
This is part of our complete JEE Main Syllabus 2027 guide.
Physical Chemistry
Tap any chapter below to open its own detailed breakdown.
| # | Unit | Topics |
|---|---|---|
| 1 | Basic Concepts in Chemistry | Mole concept, stoichiometry, laws of chemical combination |
| 2 | Atomic Structure | Bohr model, quantum numbers, orbital shapes, Aufbau principle, Hund's rule |
| 3 | Chemical Bonding & Molecular Structure | VSEPR theory, hybridization, valence bond & molecular orbital theory |
| 4 | Chemical Thermodynamics | Enthalpy, entropy, Gibbs energy, Hess's law |
| 5 | Solutions | Concentration terms, Raoult's law, colligative properties, van't Hoff factor |
| 6 | Equilibrium | Chemical & ionic equilibrium, pH, buffers, solubility product, Le Chatelier's principle |
| 7 | Redox Reactions & Electrochemistry | Electrode potentials, Nernst equation, conductance, Kohlrausch's law |
| 8 | Chemical Kinetics | Rate laws, order vs. molecularity, Arrhenius equation, activation energy |
Inorganic Chemistry
| # | Unit | Topics |
|---|---|---|
| 9 | Classification of Elements & Periodicity | Periodic trends — atomic/ionic radius, ionization enthalpy, electronegativity |
| 10 | p-Block Elements | Groups 13–18 — trends, reactivity, key compounds |
| 11 | d- & f-Block Elements | Transition metals, lanthanoids, actinoids, KMnO₄ & K₂Cr₂O₇ chemistry |
| 12 | Coordination Compounds | Werner's theory, IUPAC nomenclature, isomerism, crystal field theory |
Organic Chemistry
| # | Unit | Topics |
|---|---|---|
| 13 | Purification & Characterisation of Organic Compounds | Crystallization, distillation, chromatography, qualitative/quantitative analysis |
| 14 | Basic Principles of Organic Chemistry | Isomerism, inductive & resonance effects, hyperconjugation, reaction mechanisms |
| 15 | Hydrocarbons | Alkanes, alkenes, alkynes, aromatic compounds (benzene chemistry) |
| 16 | Organic Compounds Containing Halogens | Preparation, properties, substitution mechanisms |
| 17 | Alcohols, Phenols & Ethers | Preparation, dehydration, Reimer-Tiemann, Kolbe reaction |
| 18 | Aldehydes, Ketones & Carboxylic Acids | Nucleophilic addition, Aldol condensation, Cannizzaro, Haloform reaction |
| 19 | Organic Compounds Containing Nitrogen | Amines, diazonium salts |
| 20 | Biomolecules | Carbohydrates, proteins, vitamins, nucleic acids |
Chapter Priority
Based on past exam trends, not an officially published NTA weightage.
- Consistently high-yield: Equilibrium, Chemical Bonding, Coordination Compounds, p-Block Elements, Aldehydes/Ketones/Carboxylic Acids
- Steady, moderate presence: Thermodynamics, Electrochemistry, d- & f-Block Elements, Hydrocarbons
- NCERT-line-recall heavy: Periodicity, Basic Concepts, most of Inorganic Chemistry
How to Prepare
- NCERT line-by-line for Inorganic Chemistry — this is where direct-recall questions come from most often.
- Build named-reaction flashcards for Organic Chemistry (Aldol, Cannizzaro, Reimer-Tiemann, etc.) — these repeat almost every year.
- Don't skip numericals in Physical Chemistry (Equilibrium, Electrochemistry, Kinetics) — they're just as scoring as Physics numericals.

Frequently Asked Questions
How many questions come from Chemistry in JEE Main?
25 questions (20 MCQ + 5 Numerical Value) out of 75 total, carrying 100 of the 300 marks.
Which part of Chemistry is easiest to score in?
Inorganic Chemistry, since it's largely NCERT-based recall rather than multi-step problem-solving.
