A three-tier plan for Chemistry
Tier 1: study first
Coordination Compounds, Organic Compounds Containing Oxygen, Redox Reactions and Electrochemistry, Some Basic Principles of Organic Chemistry, Hydrocarbons, p-Block Elements and Chemical Bonding and Molecular Structure. Together these carry the largest slice of recent Chemistry papers. Aim to finish them with full question practice before touching anything else.
Tier 2: core revision
Solutions, Atomic Structure, Some Basic Concepts in Chemistry, d- and f-Block Elements, Chemical Thermodynamics and Equilibrium. Steady contributors. Revise them on a regular cycle.
Tier 3: cover after the core
Chemical Kinetics, Organic Compounds Containing Nitrogen, Classification of Elements and Periodicity, Biomolecules, Purification and Characterisation of Organic Compounds, Organic Compounds Containing Halogens and Principles Related to Practical Chemistry. Lower recent weight, but not zero. Learn the high-yield ideas and keep revision short.
Dropped chapters
NTA's JEE Main 2026 syllabus no longer includes General Principles and Processes of Isolation of Metals, States of Matter, Environmental Chemistry, Surface Chemistry, Hydrogen, s-Block Elements, Polymers and Chemistry in Everyday Life. If you see them in older papers, skip them.
Chapters gaining weight
Coordination Compounds, Some Basic Principles of Organic Chemistry and Classification of Elements and Periodicity took a bigger share of the Chemistry paper in 2024–26 than in 2022–23.
Chapters losing weight
Organic Compounds Containing Oxygen have been asked less often recently. Do not skip them, but they need not be your first priority.
