NEET Chemistry: The 180-Mark Breakdown
NEET Chemistry has 45 questions worth 4 marks each = 180 marks total. The paper draws from three roughly equal branches: Physical, Organic, and Inorganic Chemistry.
Based on the last 8 years of NEET papers:
- Physical Chemistry: 15–18 questions (~35–40%)
- Organic Chemistry: 13–15 questions (~30–35%)
- Inorganic Chemistry: 12–15 questions (~28–33%)
This distribution means no branch can be fully neglected. But within each branch, some chapters are dramatically more productive than others.
Physical Chemistry: The Calculation Core
Physical Chemistry in NEET is calculation-heavy but highly predictable. The same formulas appear in different contexts year after year.
Must-master chapters:
Mole Concept and Stoichiometry — The foundation. Without this, titration, limiting reagent, and percentage composition questions all fail. Invest heavily here early.
Chemical Equilibrium and Ionic Equilibrium — Kc, Kp, Ka, Kb, Kw, and their variations appear consistently. Buffer solutions, solubility product, and hydrolysis questions require both formula fluency and qualitative understanding.
Thermodynamics — First law applications, enthalpy calculations, Hess's law, free energy and spontaneity. 3-4 questions per paper reliably.
Electrochemistry — Nernst equation, cell potential calculations, Faraday's laws for amount of substance deposited. Appears every year.
Chemical Kinetics — Rate laws, rate constant units, half-life calculations, Arrhenius equation. 2-3 questions per paper.
Strategy: For Physical Chemistry, build formula sheets. Every chapter has 3-7 key equations. Know: the formula, its variables and units, and when each applies. Daily 10-problem practice in rotation across Physical chapters maintains fluency.
Organic Chemistry: Pattern Recognition
NEET Organic is not the arrow-pushing mechanism depth of JEE. Questions test product identification, reagent selection, and characteristic reactions.
Highest yield chapters:
General Organic Chemistry (GOC) — IUPAC nomenclature (appears every year), isomers (structural, stereo, geometric), and property prediction based on electron effects. GOC errors cascade into every other Organic chapter. Do not shortcut this.
Hydrocarbons — Alkane, alkene, alkyne reactions. Markovnikov rule, anti-Markovnikov (HBr + peroxide), ozonolysis products, Baeyer's test — 2-3 direct questions per paper.
Carbonyl Compounds — Aldehydes and ketones, carboxylic acids and their derivatives. Addition reactions, reduction, oxidation, and named reactions (Aldol, Cannizzaro). 3-4 questions reliably.
Biomolecules — Carbohydrates (reducing vs non-reducing sugars, anomers), proteins (primary/secondary/tertiary/quaternary structure, denaturation), nucleic acids (DNA/RNA differences, base pairing). 2-3 questions. Relatively factual and NCERT-direct.
Polymers — Classification (natural vs synthetic, addition vs condensation), specific polymer names and their monomers. 1-2 questions but easy marks if you've memorised the classification.
Strategy: For Organic, build a reactions summary table. Columns: compound class, common reactions, key reagents, typical NEET question type. Review weekly.
Inorganic Chemistry: NCERT Is Your Entire Strategy
Inorganic Chemistry in NEET is almost entirely drawn from NCERT. Not paraphrased, not interpreted — directly lifted from specific lines, tables, and examples.
Students who try to use supplementary resources for Inorganic typically do worse than students who master NCERT alone, because the extra information adds confusion without additional NEET-tested content.
High-yield Inorganic chapters:
Periodic Table and Periodic Properties — Trends in atomic radius, ionisation energy, electronegativity, electron affinity. Exceptions to trends are favourite question sources.
p-Block Elements — This is the largest Inorganic chapter cluster. Group 15, 16, 17, 18 elements, their hydrides, oxides, oxoacids, and physical properties. Expect 4-6 questions from here across a paper. Table-read NCERT for every element property.
d and f Block Elements — Transition metals, their variable oxidation states, colour, paramagnetism, and catalytic properties. Each characteristic has an underlying reason (electronic configuration) — learn both the fact and the reason.
Coordination Compounds — IUPAC nomenclature of coordination compounds, isomerism (geometric, optical, ionisation, linkage), bonding theories (VBT and CFT qualitatively). 2-3 questions per paper.
The NCERT rule for Inorganic: Read every sentence. Every unusual property, every exception, every specific fact in a comparison table — these are NEET questions waiting to be asked. The students who score 40+ in Inorganic are the ones who treated NCERT Inorganic like a precision instrument, not background reading.
Chemistry Scoring Targets by Branch
| Branch | Target marks (out of 45/Q) | Key lever | |--------|--------------------------|-----------| | Physical | 14–16 questions correct | Formula fluency + problems | | Organic | 11–13 questions correct | Pattern recognition | | Inorganic | 10–12 questions correct | NCERT mastery |
Achieving these targets = 140–164 Chemistry marks — highly competitive territory.
