NEET Chemistry questions, chapter by chapter
Physical, organic and inorganic chemistry, with every numerical worked in full.
NCERT Class 11
Chemical Bonding and Molecular Structure
Tests how precisely a student applies VSEPR theory, hybridisation, and molecular orbital theory to predict molecular shape, bond order, and polarity. Most NEET marks are lost confusing electron-domain geometry with molecular shape, forgetting lone-pair placement rules, or assuming polar bonds always give a polar molecule.
9 questions
Equilibrium
NEET tests this chapter through Kc/Kp calculations, Le Chatelier predictions, and ionic equilibrium numericals: pH of weak acids and strong bases, buffers, and Ksp–solubility. Marks are lost by forgetting stoichiometric powers in K, mixing ln with log in ΔG° = −RT ln K, and not accounting for neutralisation before applying the buffer equation.

Organic Chemistry – Some Basic Principles and Techniques
Tests IUPAC nomenclature, the electronic displacement effects (inductive, resonance, hyperconjugation) that govern carbocation and reaction-intermediate stability, structural isomer counting, and purification technique selection. Most NEET marks are lost applying lowest-locant rules in the wrong order (multiple bonds before prefixes such as chloro-), or confusing which effect (inductive vs resonance) explains a given stability trend.
9 questions
Some Basic Concepts of Chemistry
NEET uses this chapter for fast mole-concept arithmetic: counting particles, limiting reagents, empirical formulae and concentration conversions (molarity, molality, mole fraction). Marks are lost to unit slips (g vs kg, solution vs solvent mass), to skipping the limiting-reagent check, and to counting molecules when the question asks for atoms.
9 questions
Thermodynamics
NEET tests the first law sign convention, ΔH–ΔU conversion, Hess's law and bond-enthalpy arithmetic, reversible work, and ΔG = ΔH − TΔS spontaneity logic. Most lost marks come from sign errors (work done by vs on the system), kJ–J mismatches, counting liquid water as gas in Δng, and forgetting stoichiometric coefficients in Hess's law.

Practising is step one. Knowing what to practise next is the hard part.
