About this IIT JEE Chemistry practice test

IIT JEE Chemistry rewards balanced preparation across Physical, Organic and Inorganic. This practice test follows that 1:1:1 split and is structured around the most-tested JEE chapters — Mole Concept, Thermodynamics, Equilibrium, Electrochemistry, Hydrocarbons, Haloalkanes & Haloarenes, Aldehydes-Ketones, Coordination Compounds, p-Block and d-Block Elements. The starter set mixes calculation-based Physical questions with reaction-based Organic questions and fact-based Inorganic questions so you can do a full spectrum drill in one session. Each generated question comes back with the reasoning and key formula used.

This page is built for students looking for iit jee chemistry practice test, chapter practice, and quick school exam revision.

Why this practice page is useful

Balanced practice across all three Chemistry verticals — Physical (calculations), Organic (mechanisms) and Inorganic (facts).

Mock paper-style mix lets you simulate the real JEE Chemistry section under timer.

Replace the starter with NCERT exemplar or previous-year JEE questions for chapter-wise drilling.

Answer key & quick explanations

Short answers for the sample questions above. Use this to self-check before generating a fresh AI-built mock test.

  1. Moles in 36 g H₂O: n = mass/molar mass = 36/18 = 2 mol.
  2. Le Chatelier's principle: If a system at equilibrium is disturbed, it shifts to oppose the change. Eg. ↑ pressure favours the side with fewer moles of gas.
  3. pH of 0.001 M HCl: [H⁺] = 10⁻³ → pH = 3.
  4. Hund's rule: Pairing in degenerate orbitals begins only after each is singly occupied with parallel spins.
  5. Mn in KMnO₄: +1 + x + 4(−2) = 0 → x = +7.
  6. IUPAC name: Propan-2-ol.
  7. SN1 vs SN2: SN1 — two-step, carbocation intermediate, 3° substrate. SN2 — one-step, backside attack, 1° substrate, inversion of configuration.
  8. Electrochemical cell: Device that converts chemical energy to electrical energy. Eg. Daniell cell (Zn|Zn²⁺||Cu²⁺|Cu).
  9. C₂H₅Br + alc. KOH: Elimination → ethene (CH₂=CH₂) + KBr + H₂O.
  10. Markovnikov's rule: In addition of HX to an unsymmetrical alkene, H goes to the carbon with more H atoms. Eg. CH₃CH=CH₂ + HBr → CH₃CHBrCH₃.
  11. Ionic vs covalent: Ionic — electron transfer, electrostatic attraction (NaCl). Covalent — electron sharing (Cl₂).
  12. Lattice energy: Energy released when 1 mole of an ionic crystal forms from gaseous ions. Increases with higher charge and smaller ionic radius.
  13. Faraday's 1st law: Mass deposited ∝ quantity of charge passed (m = ZQ).
  14. Aluminium ores: Bauxite (Al₂O₃·2H₂O), Cryolite (Na₃AlF₆).
  15. NH₃ and BF₃ hybridisation: NH₃ — sp³ (one lone pair, pyramidal). BF₃ — sp² (trigonal planar).
