National Eligibility Cum Entrance Test Chemistry Weightage
Are you getting ready for the NEET 2025 exam? Understanding the chapter-wise weightage is like having a map for your preparation journey. NEET Chemistry syllabus is divided into Inorganic, Physical, and Organic sections. Knowing which chapters have more weightage can make your study plan more effective. The chemistry section of NEET has 45 questions. The three sub-sections of Chemistry; Inorganic, Organic and Physical, have nearly equal weightage in the question paper. Candidates can refer to the table below to know the weightage of individual chapters. Know the NEET Chemistry chapter-wise weightage.
| Chemistry Section | Weightage |
|---|---|
| Inorganic Chemistry-I | 22% |
| Inorganic Chemistry-II | 12% |
| Organic Chemistry-I | 8% |
| Organic Chemistry-II | 26% |
| Physical Chemistry-I | 17% |
| Physical Chemistry-II | 15% |
The NEET 2025 exam is likely to be conducted by NTA in the first week of May 2025. The NEET 2025 syllabus is expected to remain the same as last year, which underwent major changes. Based on the revised syllabus, and the NEET 2024 analysis, we have prepared the NEET 2025 chapter-wise weightage. Take a look at the chapter-wise weightage for NEET 2025 PDF by NTA here on this page.
Over 14 units are included in the NEET Chemistry class 11 syllabus. A few important topics from class 11’s Physical Chemistry topics are Basic Concepts of Chemistry, Chemical Bonding, and Chemical Equilibrium. Thermodynamics, Chemical Equilibrium, Chemical Bonding and Molecular Structure have the highest weightage of 8%, 6%, and 5% respectively.
NEET Chemistry class 12 syllabus includes 16 chapters. Chemical Kinetics from Physical Chemistry and Co-ordination Compounds from Inorganic Chemistry are important topics. Coordination Compounds have the highest weightage of 9%. p-Block Elements carry an equal weightage of 5% of questions.
