The National Medical Commission (NMC) removed some topics from NEET syllabus in 2024. There are around nine chapters in Chemistry which have been removed. In Chemistry, these chapters or topics were removed from the units given in the table below.

Units	Topics
Some Basic Concepts of Chemistry	General Introduction: Important and scope of chemistry.
Structure of Atom	Atomic number, isotopes and isobars, Concept of shells and subshells, dual nature of matter and light.
Some p-Block Elements	Important compounds of silicon and a few uses: silicon tetrachloride, silicones, silicates and zeolites, their uses.
Organic Compounds Containing Nitrogen	Cyanides and Isocyanides- will be mentioned at relevant places.
Environmental Chemistry	Environmental pollution: Air, water and soil pollution, chemical reactions in atmosphere, smogs, major atmospheric pollutants; acid rain ozone and its reactions, effects of depletion of ozone layer, greenhouse effect and global warming-pollution due to industrial wastes; green chemistry as an alternative tool for reducing pollution, strategy for control of environmental pollution.
Polymers	Classification- Natural and synthetic, methods of polymerization (addition and condensation), copolymerization. Some important polymers: natural and synthetic like polyesters, bakelite; rubber, Biodegradable and non-biodegradable polymers.
Chemistry in Everyday Life	Chemicals in medicines- analgesics, tranquilizers, antiseptics, disinfectants, antimicrobials, antifertility drugs, antibiotics, antacids, antihistamines. • Chemicals in food- preservatives, artificial sweetening agents, elementary idea of antioxidants. • Cleansing agents- soaps and detergents, cleansing action.
Surface Chemistry	Adsorption-physisorption and chemisorption; factors affecting adsorption of gases on solids, catalysis homogeneous and heterogeneous, activity and selectivity: enzyme catalysis; colloidal state: distinction between true solutions, colloids and suspensions; lyophilic, lyophobic multimolecular and macromolecular colloids; properties of colloids; Tyndall effect, Brownian movement, electrophoresis, coagulation; emulsions- types of emulsions.
Haloalkanes and Haloarenes	· Haloalkanes: Nomenclature, nature of C –X bond, physical and chemical properties, mechanism of substitution reactions. Optical rotation. · Haloarenes: Nature of C-X bond, substitution reactions (directive influence of halogen for monosubstituted compounds only). · Uses and environmental effects of – dichloromethane, trichloromethane, tetrachloromethane, iodoform, freons, DDT.
