About this NEET Chemistry practice test

NEET Chemistry rewards aspirants who have read every line of the NCERT Class 11 and 12 textbooks. This practice test mirrors that NCERT-heavy bias — the starter set covers Mole Concept, Equilibrium, Electrochemistry, p-Block, Coordination Compounds, Hydrocarbons, Alcohols, Aldehydes-Ketones and Biomolecules. NEET Chemistry questions tend to be a mix of direct fact-recall (“which oxide is amphoteric?”) and short calculation (“find the molarity”), and the starter reflects that. Each generated question links the answer back to a specific NCERT concept where possible.

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. Atoms in 4 g He: Number of moles = 4/4 = 1 → atoms = 1 × 6.022×10²³ = 6.022×10²³.
  2. Law of conservation of mass: Mass can neither be created nor destroyed in a chemical reaction.
  3. pH of 0.01 M NaOH: [OH⁻] = 10⁻² → pOH = 2 → pH = 14 − 2 = 12.
  4. Hybridisation of CH₄: sp³ (tetrahedral, 109.5°).
  5. Hund's rule: Pairing of electrons in degenerate orbitals begins only after each is singly occupied.
  6. Alkane vs alkene vs alkyne: Alkane — only C–C single bonds (CnH2n+2). Alkene — one C=C (CnH2n). Alkyne — one C≡C (CnH2n−2).
  7. IUPAC name: But-2-ene.
  8. Markovnikov's rule: In addition of HX to an unsymmetrical alkene, H attaches to the carbon with more hydrogens.
  9. Electrolysis: Decomposition of an electrolyte by passing direct current. Industrial use: extraction of aluminium from molten alumina.
  10. Iron ores: Haematite (Fe₂O₃), Magnetite (Fe₃O₄).
  11. Sigma vs pi bond: Sigma — axial overlap, stronger, free rotation. Pi — lateral overlap, weaker, no free rotation.
  12. Molarity: M = moles of solute / volume of solution in litres.
  13. Biomolecules: Carbohydrates — energy source. Proteins — build body tissues / enzymes.
  14. Coordination compound: A molecule containing a central metal ion bonded to ligands. Eg. [Cu(NH₃)₄]SO₄.
  15. Vitamin C: Functions in collagen synthesis and immunity; sources — amla, citrus fruits.
