JEE Main 2026 Chemistry Top 15 Chapters for Session 1
JEE Main 2026 Session 1 exam is approaching soon. Here are the top 15 important Chemistry chapters must focus on for better results.
The JEE Main 2026 Session 1 is about to begin, and candidates are now entering the most important part of their preparation. Out of all three subjects, Chemistry remains one of the most scoring sections, if students prepare tactically and concentrate on the Right chapters. As per the analysis of academic experts and toppers, focusing on all the high-weightage and concept-based topics can rake in good marks and an overall percentile.
The NCERT chemistry textbooks are the backbone of JEE preparation in Chemistry. In general, the paper is composed of a proper balance between Physical Chemistry, Organic Chemistry, and Inorganic Chemistry, with both theoretical and analytical questions. Most of the questions asked in JEE Main are directly or indirectly based on NCERT concepts, especially in Inorganic Chemistry. They should also develop the habit of practising previous years’ papers, mock tests, and chapter-wise numerical problems, which can help them in gauging speed, accuracy, and time management.

JEE Main 2026 Chemistry Preparation Tips
Chemistry is one of the toughest subjects in JEE, but you must adhere to these smart preparation tips to make your concepts strong in Chemistry and enhance your score in JEE Main.
Most JEE questions are directly from NCERT textbooks, so concentrate on them.
Make short notes and flashcards for formulas and reactions so you can revise quickly.
To Get Familiar With the Exam Pattern and Marking Scheme by solving previous Year Papers to know the Exam Tendency and Weightage.
Practice numerical problems from Physical Chemistry every day.
Revise Mechanisms of Organic Reactions and Name Reactions regularly.
Learn Inorganic through Periodic Trends and From NCERT.
Attempt mock tests every week to check your preparation and for speed improvement.
Don’t cram at the end — have clarity of concepts instead.
Be consistent, utilise time in a better way, and think positively.
A well-balanced preparation strategy combining conceptual learning, practice, and mock analysis can ensure a strong performance in Chemistry and give a significant boost to the overall JEE Main 2026 percentile.
