NEET UG Chemistry Syllabus 2025: The National Eligibility cum Entrance Test (NEET-UG) is a highly competitive examination conducted annually by the National Testing Agency (NTA) for students seeking admission to MBBS, BDS, and other allied health courses in various government and private medical colleges in India. Aspiring candidates who wish to pursue a career in the medical field need to have a thorough understanding of the NEET chemistry syllabus.
The NEET chemistry syllabus for the year 2025 comprises topics from both Class 11 and 12. The syllabus has been designed to test the candidates’ knowledge and comprehension of basic chemistry concepts, principles, and applications. The NEET chemistry syllabus is divided into three sections, namely physical chemistry, organic chemistry, and inorganic chemistry.
