JEE Main 2024 Chemistry chapter-wise analysis

JEE Main 2024 had 438 Chemistry questions across all shifts. The three chapters with the most were p-Block Elements (40, 9.1%), Coordination Compounds (38, 8.7%) and Organic Compounds Containing Oxygen (32, 7.3%).

Against 2023, Coordination Compounds (+4.4 points), p-Block Elements (+3.5 points) and Solutions (+3.1 points) gained share while Some Basic Principles of Organic Chemistry (-1.7 points) lost share.

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 were asked in 2023 but not in 2024, and are no longer in the JEE Main 2026 syllabus.

The most repeated concepts that year were Concentration Terms (9), Percentage Composition and Equivalent Weight (7) and Applications of Crystal Field Theory (6).

Most repeated concepts

The concepts JEE Main asks most.

In the source data the Chemistry counts for 2024 and 2025 look unevenly split between the two years, so read those two years together rather than as separate trends.

Counts are compiled from Edurack's JEE Main last five-year analysis (2022–2026) and count questions across all shifts and sessions of each year. Because the number of shifts changes every year, trends compare each chapter's share of the paper among chapters still in the syllabus, not raw counts. Past frequency is a trend guide, not a prediction. Chapters marked "not in syllabus" are absent from NTA's JEE Main 2026 syllabus; always check the latest NTA syllabus before skipping a chapter.
