JEE Main Chemistry Syllabus 2026 PDF, Physical, Organic, Inorganic Topics

The JEE Main 2026 Chemistry syllabus is anticipated to be published shortly by the NTA on its official portal, jeemain.nta.nic.in. Since the 2025 edition saw minimal changes, many experts expect the 2026 syllabus to remain stable. In 2025, several topics—such as Surface Chemistry, States of Matter, General Principles and Processes of Isolation of Metals, s‑Block Elements, Hydrogen, Environmental Chemistry, Alcohols, Phenols & Ethers, and Polymers—were removed .

The core content will still cover subjects like Isolation of Metals, s‑Block Elements, Hydrogen, Environmental Chemistry, Alcohols, Phenols, Ethers, and Polymers.

The comprehensive syllabus is expected to be divided into three sections:

• Section A: Physical Chemistry
• Section B: Inorganic Chemistry
• Section C: Organic Chemistry 

Each section will include topic-wise weightage data to help students strategically plan their studies. While concentrating on high-yield chapters is wise, a complete understanding of the full syllabus remains essential for achieving top scores.

JEE Main Chemistry Syllabus 2026 Overview

The NTA is anticipated to release the JEE Main 2026 Chemistry syllabus soon. Meanwhile, applicants can still access the previous year’s Chemistry syllabus on the official JEE Main website. The syllabus is structured into three parts: 

Section A: Physical Chemistry
Section B: Inorganic Chemistry
Section C: Organic Chemistry.

Until the official 2026 syllabus is published, candidates should study all topics covered in the NCERT curriculum for classes 11 and 12, following the latest (2025) syllabus. Once the 2026 syllabus is released, students should adjust their preparation accordingly.

JEE Main Chemistry Preparation Tips 2026

To perform well in the JEE Main Chemistry section, candidates must follow a strategic and consistent preparation plan. Here are some essential tips to enhance your performance:

1. Understand the Syllabus:
Familiarize yourself thoroughly with the complete Chemistry syllabus, which includes Physical, Organic, and Inorganic Chemistry. Organize your study schedule based on topic-wise weightage to manage time efficiently and focus on high-priority areas.

2. Build Conceptual Clarity:
Rather than relying on rote memorization, strive to understand the core principles behind chemical reactions, theories, and mechanisms. A clear grasp of fundamentals will make it easier to apply concepts while solving problems.

3. Practice Regularly:
Solve a variety of questions consistently, including previous years’ papers and sample problems. Regular practice, especially in Organic and Physical Chemistry, helps strengthen your grasp and improve speed and accuracy.

4. Make Summary Notes:
Prepare concise notes highlighting key reactions, mechanisms, and formulas. These notes will be extremely useful for quick revision before the exam.

5. Use Visual Aids:
Incorporate flowcharts, reaction diagrams, and summary tables—especially for Organic Chemistry—to simplify complex topics and improve retention through visual learning.

6. Focus on NCERT Books:
Give special attention to NCERT textbooks, particularly for Inorganic Chemistry. Most questions in this section are directly based on NCERT, making it a crucial resource for conceptual clarity.

7. Join Study Groups:
Engaging in group discussions with classmates or peers helps reinforce your understanding. Teaching or explaining concepts to others is a powerful way to retain information.

8. Take Mock Tests:
Attempt mock tests regularly to simulate real exam conditions. Analyze your performance after each test, identify weak areas, and revise accordingly to improve your overall readiness.
