NEET Chemistry Syllabus

JEE Mains & Advanced

NEET Chemistry for MBBS Exams (Introduction)

The Chemistry Syllabus of NEET is made up of the Physical Chemistry section, Inorganic Chemistry section, and Organic Chemistry section from Classes 11 and 12. The Chemistry section of NEET is considered the scoring section. For students, chemical reactions, mechanisms, compositions, and chain reactions are usually the minimum, fundamental concepts to be covered. NEET questions are often framed directly from concepts found in NCERT textbooks. In addition, previous years' trends suggest that students are evaluated in the Chemistry section with more or less the same type of questions and varying levels of complexity.

Before beginning your NEET preparation, it is highly advisable to thoroughly examine and comprehend the topics covered in the NEET chemistry syllabus. A more effective way to begin your NEET preparation with the Chemistry syllabus is by conducting an analysis on the NEET question papers. Most NEET candidates are comfortable with the Chemistry section compared to the Physics and Biology sections.
