JEE Main Chemistry syllabus is divided into three sections: organic, inorganic and physical. NTA JEE Main chemistry syllabus is strictly based on CBSE Class 11 & 12 NCERT, making it predictable and syllabus-driven. Compared to the Physics and Maths sections, Chemistry is often considered high-scoring when prepared strategically.

FAQs
Yes. NCERT is sufficient for Inorganic and most Organic Chemistry questions.
Ans. Due to direct NCERT-based questions, Inorganic Chemistry is considered the easiest.
Ans. Yes. It is fully aligned with the CBSE Class 11 & 12 syllabus.
Ans. As of now, no major changes have been announced. Students should follow the official NTA syllabus.
Ans. As per the recent exam pattern, a total of 25 questions are in the JEE Main Chemistry section. 20 questions are compulsory, and 5 are numerically-based optional questions.
Ans. JEE Main inorganic chemistry core areas are as follows:-
1. Periodic table and periodicity
2. p‑block, d‑block & f‑block elements
3. Coordination compounds (nomenclature, isomerism, theories)
Ans. Yes. The chemistry section is found to be high scoring by many students due to theory-based questions in the organic and inorganic sections. Whereas Maths and Physics may be more calculation‑intensive.
Ans. Yes. You should cover the entire JEE Main syllabus while thoroughly revising the NCERT textbooks. First, complete the high-weightage and scoring topics, which can help improve your score. But it is important to ensure that all core concepts are covered for a strong foundation.
