The NTA has released the JEE Mains 2026 Chemistry Syllabus on the official website jeemain.nta.nic.in. The official JEE Main Chemistry syllabus by NTA includes chapters from both Class 11 and Class 12 NCERT textbooks. There have been no changes in the JEE Main Syllabus for Chemistry 2026. It covers three major branches: Physical Chemistry, Inorganic Chemistry, and Organic Chemistry, along with practical-based topics.
- The physical chemistry (30-35% weightage) portion includes chapters like atomic structure, chemical bonding, thermodynamics, equilibrium, kinetics, and electrochemistry.
- Inorganic Chemistry (30-35% weightage) focuses on periodic classification, p-block, d-block, f-block elements, and coordination compounds.
- Organic chemistry (30-35% weightage) covers hydrocarbons, functional groups, biomolecules, and practical experiments.
Chemistry is often considered the most scoring subject for JEE Main because it contains more theoretical questions compared to the calculation-heavy subjects of Physics and Mathematics. In recent years (especially 2024–2025 sessions):
- Physical Chemistry has seen a rise in numerical/graph-based questions.
- Inorganic Chemistry dominates with fact-based/assertion-reason questions.
- Organic Chemistry focuses on mechanisms, named reactions, and biomolecules.

JEE Main Chemistry Syllabus FAQs
Ques. What is the 80/20 rule in JEE Mains?
The 80/20 rule in JEE Main means that around 80% of the questions usually come from 20% of the high-priority chapters. This rule helps students focus on the most scoring topics, improve accuracy, and reduce unnecessary study load. It is commonly used for smart revision and strategic preparation.
Ques. Is P-Block removed from JEE Main Chemistry 2026?
No, P-Block is not removed from JEE Main Chemistry 2026. Only a few subtopics have been reduced, but core concepts, trends, and key reactions are still included in the syllabus.
Ques. Why is it important to know the weightage of topics in the JEE Main Chemistry syllabus?
Knowing the topic-wise weightage in JEE Main Chemistry helps you prioritize high-scoring chapters, plan your study time better, and focus on the areas that contribute the most marks. It directly improves exam strategy, time management, and overall score.
Ques. Is Surface Chemistry removed from JEE Main Chemistry 2026?
Yes, Surface Chemistry has been removed from the JEE Main syllabus. It was officially removed in 2024, and the same change is expected to continue for JEE Main 2026, so the chapter is not required for preparation.
I'm a dropper for the JEE Main, and my chemistry is very weak. How much chemistry syllabus should I cover?
Students often wonder which chapters they should cover in JEE Chemistry syllabus or how they will clear JEE if their Chemistry is very weak. We have researched various students' discussion forums.
As per Quora user Kumar Rishik: This is a very common but relevant question because during my preparations I too observed my batch mates encountering the same issue.
As per another user Urvi Nahata: When I was preparing for JEE i realised that to score in chemistry is easy that's why I started studying that. I made short notes, and revised everyday. Same I will recommend to you. Go for 100% syllabus in your chemistry part. Yes you can leave certain topics which are really difficult but don't leave anything just because it is boring.
What is the Weightage for JEE Main Chemistry Syllabus 2026?
According to the analysis of recent JEE Main papers (2024-2025):

JEE Main Chemistry Marks Vs Percentile FAQs
Ques. Is 120 a good score in JEE Mains?
Ans. If a candidate is scoring 120 marks in JEE Mains, it will be considered a decent score. But if it is good or not, it will depend upon its difficulty level, category and the desired college by the candidate.
- As the total marks are 300, scoring 120 marks will correspond to a percentile between 90-93.
- A score of 120 marks will be enough for lower-branch NITs or state colleges, but not for the top NITs or IIITs in CSE or ECE.
Ques. What percentile is 70 marks in JEE?
Ans. As per the previous years' JEE Main marks vs percentile analysis, students will get around 70-80 percentile in JEE Main for scoring 70 marks in the examination.
