Chemistry Syllabus Structure — Units and Approach

Chemistry in NEET UG 2026 is divided into three clear sections. Physical Chemistry (Units 1–8) focuses on calculations and concepts. Inorganic Chemistry (Units 9–12) is more about clarity and recall. Organic Chemistry (Units 13–20) requires a strong understanding of reactions and mechanisms.
