JEE Main Chemistry is 25 questions and 100 marks — 20 MCQ plus 5 numerical — split across Physical, Inorganic and Organic Chemistry. It is widely considered the highest-scoring and fastest of the three JEE Main sections: Inorganic is recall-driven, Organic is mechanism-driven, and only Physical demands sustained calculation. Finishing Chemistry quickly is what buys you time for Physics and Maths.
The three branches #
| Branch | Approx. questions | Character |
|---|---|---|
| Physical Chemistry | 8–9 | Numerical; formula-driven |
| Inorganic Chemistry | 8–9 | Recall; fastest to answer |
| Organic Chemistry | 8–9 | Mechanisms and conversions |
Physical Chemistry #
Some Basic Concepts · Atomic Structure · Chemical Bonding and Molecular Structure · Chemical Thermodynamics · Solutions · Equilibrium · Redox Reactions and Electrochemistry · Chemical Kinetics
Heaviest: Thermodynamics, Equilibrium, Electrochemistry, Chemical Kinetics, Solutions.
Inorganic Chemistry #
Classification of Elements and Periodicity · Hydrogen and s-Block · p-Block Elements · d- and f-Block Elements · Coordination Compounds · Environmental Chemistry
Heaviest: Coordination Compounds, p-Block, Chemical Bonding.
Organic Chemistry #
Purification and Characterisation of Organic Compounds · Basic Principles of Organic Chemistry · Hydrocarbons · Organic Compounds containing Halogens · containing Oxygen · containing Nitrogen · Biomolecules · Principles related to Practical Chemistry
Heaviest: General Organic Chemistry, Oxygen-containing compounds, Biomolecules.
- Chemistry is your time bank. Candidates who finish it in 45 minutes give themselves the margin to survive a hard Maths or Physics section.
- Coordination Compounds is the single highest-yield Inorganic chapter — nomenclature, isomerism, CFT and magnetic moment recur every year.
- Learn Organic through mechanism, never through memorised reaction lists. Conversions are the standard JEE question type and lists fail on unfamiliar ones.
- Practical Chemistry (salt analysis, tests) is a small, ignored unit that appears.
- Physical Chemistry numericals are the only part needing the on-screen calculator. Practise there.
