The deleted syllabus of JEE Mains 2026 Chemistry are States of Matter, Surface Chemistry, Environmental Chemistry, Polymers, Chemistry in Everyday Life, Hydrogen, s-Block Elements, Group 13 & 14 p-block Elements and Alcohols, Phenols & Ethers. These chapters were removed to cut down on topics that carry less weight in the exam and mainly require rote memorization.
- For JEE Main 2026, focus more on Physical Chemistry topics like Thermodynamics, Equilibrium, Electrochemistry and Kinetics and in Organic Chemistry, on Carbonyls, Amines, Haloalkanes and Hydrocarbons.
- In Inorganic Chemistry, skip basics like Hydrogen, s-Block and Group 13 & 14 p-Block, and just concentrate on Coordination Compounds, d-Block and f-Block elements.

Key Summary
- Some of the topics that have been removed are States of Matter and Physical Chemistry in addition to Hydrogen and Eco-Chemistry. Macromolecules, Chemistry in Everyday Life and Alcohols-Phenols-Ethers are also removed. You also can skip s-Block Elements and Group 13 & 14 p-Block along with Extraction of Metals as they are removed.
- Older models such as Thomson’s and Rutherford’s in addition to dimensional analysis concepts have been removed from Class 11 Chemistry.
- The topics that are important are Thermodynamics and Equilibrium. Additionally Electrochemistry and Kinetics continue to be essential and hold significant.
- You need to lay emphasis on topics like Haloalkanes and Haloarenes. Similarly, focus on Aldehydes and Ketones along with Carboxylic Acids and Amines. The practical chapters such as Polymers and Everyday Chemistry have been removed.
- You do not need to rely on heavy memorisation since only Coordination and d-Block, f-Block along with specific p-Block groups (15-18) are left.
Deleted Syllabus of JEE Mains 2026 Chemistry: List of Removed Chapters & Topics
- Basic Inorganic topics like Hydrogen, s-block and p-block have been removed.
- Chapters that are more application-based, like Polymers, Environmental Chemistry and Chemistry in Everyday Life, are also not included in the JEE exam anymore.
Even some older or introductory concepts like early atomic models, dimensional analysis, states of matter and surface chemistry have been cut out to reduce unnecessary memorisation has reduced the JEE Mains 2026 Chemistry syllabus to match the updated NCERT Class 11 and 12 books. Some topics have been removed, and even the chapters that were already cut earlier won’t be a part of JEE Mains 2026. Nonetheless, candidates must continue to read NCERT textbooks for conceptual understanding, as certain fundamental concepts might indirectly aid in grasping other Chemistry topics.
Here’s the complete list of what’s not included anymore.

JEE Mains 2026 Chemistry Syllabus: Updated Chapter-Wise Topics to Study
The JEE Mains 2026 Chemistry syllabus has been revised by NTA. The purpose is to match the new NCERT Class 11 and 12 textbooks. Some chapters like Surface Chemistry and Polymers among a few others are no longer included. But all the main topics in Physical as well as Organic and Inorganic Chemistry that really matter for engineering prep are still part of the JEE Main exam syllabus.
- In Physical Chemistry crucial chapters are Thermodynamics and Equilibrium. You also need to focus on Electrochemistry and Chemical Kinetics as they are still very significant.
- In Inorganic Chemistry the focus has shifted to the Periodic Table as well as Coordination Compounds. You also need to prepare carefully topics like d-Block and f-Block elements.
- In Organic Chemistry you will still cover reaction mechanisms like Haloalkanes and Haloarenes along with Aldehydes and Ketones among a few others. However chapters like Polymers, and Alcohols-Phenols-Ethers in addition to Chemistry in Everyday Life have been removed.

Impact of the Deleted Syllabus of JEE Mains 2026 Chemistry Preparation
Since chapters such as Surface Chemistry and Environmental Chemistry among others (Groups 13 & 14) have been removed from the JEE Mains 2026 Chemistry syllabus the load is lighter now. The syllabus is more streamlined and so it is easier for you toconcentrate on the key topics more .
Let us see what this means for your study plan.
1. Less rote learning & more conceptual clarity
Previously, subjects such as Environmental Chemistry or Chemistry in Everyday Life required extensive memorisation of insignificant details that seldom helped in solving problems. Eliminating them allows you to focus more on sections that truly develop ideas, such as Thermodynamics, Equilibrium, Electrochemistry and Organic Reaction Mechanisms
2. Better time management during preparation
On average, the deleted chapters could take 4-6 weeks of preparation if you count note-making, revision and practice questions. By eliminating these topics, NTA has helped students free up study time that you can now redirect to high-weightage topics.
For example, Instead of spending weeks on Polymers and Everyday Chemistry, you can now focus on Chemical Kinetics or Coordination Compounds, which frequently appear in the JEE Main exam.
3. Shift of weightage towards core topics
The JEE Mains paper has always given higher importance to Physical and Organic Chemistry, while Inorganic relied heavily on memorisation. Because of the big parts of Inorganic removed, the topics that carry more weightage in your exam are:
- Numerical-heavy Physical Chemistry (Electrochemistry, Thermodynamics, Chemical Kinetics).
- Mechanism-based Organic Chemistry (Aldehydes, Ketones, Amines, Haloalkanes, Hydrocarbons).
4. Easier revision cycles
Your revision cycles can become sharper and faster with a lighter syllabus. You can repeatedly revise high-weightage areas instead of spending days revising low-value chapters.
- A complete Chemistry revision that once took you 25-30 days can now be done in 15-18 days.
- This gives you more flexibility to attempt mock tests and strengthen weak areas.
5. Competitive advantage for serious aspirants
Many students might still be confused about whether to study deleted topics “just in case.” But being clear on what is officially excluded means you will not waste energy. If you stick to the updated syllabus you will have an advantage:
- You save study hours.
- You focus on exam-relevant content.
- You improve accuracy in the actual test because your revision is targeted.

Ans. Yes. Just like Chemistry certain chapters and sub-topics in Physics such as Communication Systems and some portions of Experimental Skills and Mathematics like Mathematical Induction and Mathematical Reasoning have been deleted in JEE Mains 2026. The exam now focuses on NCERT-based concepts that are high-value in nature.
Ques. Will the JEE Advanced 2026 syllabus also follow the same deleted topics as JEE Mains 2026?
Ans. Not exactly. The revised NCERT Class 11 and 12 syllabus is adopted by JEE Mains. But the JEE Advanced exam is set by IITs and hence it usually has a much broader syllabus. Some topics that are deleted from JEE Mains may still exist in JEE Advanced 2026. Thus aspirants who intend to target IITs must certainly check the official JEE Advanced syllabus PDF.
