NEET Chemistry Notes For Class 11

NEET Chemistry Class 11 Syllabus 2026-27 includes 10 units. This year some chapters like s-Block, Hydrogen, States of matter, and Environmental Chemistry have been removed from NEET Chemistry Class 11 syllabus.

After the release of the revised chemistry syllabus by the National Medical Commission (NMC), you have to prepare fewer chapters for NEET 2026-27. Chemical Bonding and Molecular Structure, Chemical Thermodynamics, Some basic concepts of organic chemistry, and Chemical Equilibrium are some high-weightage chapters from the class 11 chemistry syllabus for NEET.

NEET exam pattern has been revised this year. To prepare your best, you must have the best study material for chemistry syllabus. Along with that, you must solve NEET Chemistry mock tests and previous year's papers regularly.
