NEET Chemistry Syllabus 2026: Chapter-wise Weightage

The table brings the topics from the Chemistry section in NEET. Check below the NEET Chemistry chapter-wise weightage below- 

Note: The above table carries topic-wise weightages based on last year's NEET exam. Candidates may use it for reference by omitting the removed topics.

How to Prepare for NEET Chemistry Section?

Preparing for the NEET Chemistry section may be different from that of the other two sections. First and foremost, you should be thorough with the NEET Chemistry syllabus and question types. Have a look at the NEET Chemistry preparation tips:

• The first and foremost step is to complete the syllabus.
• After completing the preparation, you are advised to take a preliminary mock test to identify your preparation level. Based on that, you can identify your strong and weak areas. You should spend more time improving the weak areas, and if, after multiple attempts, you are unable to improve, then you may omit those topics and work on your strong suits, and those topics that have a scope for improvement.
• After reading the textbooks and completing the NCERT, you can solve the NCERT Exemplar and the best books for NEET Chemistry preparation. After completing each chapter, solve the worksheets or practice papers to test your preparation level.
• After completing the NEET Chemistry preparation, the best way to check the preparation level is by taking sectional mock tests. This will help you assess your preparation level and help plan the further strategy. After taking the mock tests, ensure that it is checked by your teachers and a proper analysis is given on them.
• Solving the NEET question papers will give exposure to candidates about the Chemistry question types and topics covered. Hence, it is one of the golden rules of preparation. 

As per the NEET analysis of last year, the difficulty level of the Chemistry chapters for NEET was easy to moderate. The Chemistry section was a balanced mix of physical, organic, and inorganic chemistry. The questions ranged from straightforward factual questions based on direct concepts from the NCERT textbooks to more application-based questions. The highest weightage was given to 'Organic Chemistry: Some Basic Principles and Techniques. Out of 50 questions, nine were numerical-based, seven involved matching the following, and five were statement-based.
