Chemistry — Inorganic Chemistry for the NEET Exam — California candidates

5% of the NEET test plan. p-block elements, d-block and f-block elements, hydrogen, s-block elements, coordination compounds, and chemical bonding — approximately 35% of NEET Chemistry. Calibrated for Californian candidates.

Behind every published pass rate is a distribution of which topics caused most of the failures. This is one of those topics. Chemistry — Inorganic Chemistry sits at roughly 5% of the National Eligibility cum Entrance Test content distribution — Inorganic Chemistry in NEET is the most memorisation-dependent subject but is highly rewarding for well-prepared students. p-block reactions, coordination chemistry, and chemical bonding questions are NCERT-derived and do not require creative reasoning — they require accurate, detailed recall. VSEPR geometry and hybridisation questions appear in nearly every NEET paper. Pass rates for the NEET are published annually by the awarding body and vary by cohort and locale. For California candidates preparing for NEET, the calibration of study to local context matters: California is the largest U.S. testing market for NCLEX, MCAT, SAT, and ACT. The CA Board of Registered Nursing has notoriously long endorsement timelines (8–14 weeks).

Pass rates for NEET (California, USA) are published periodically by the awarding body.

Common failure modes

These are the patterns that cause most candidates to lose marks on this topic. Recognising them in advance is half the work.

  • !Wrong VSEPR geometry when lone pairs are present — SF₄ is see-saw (not square planar), ClF₃ is T-shaped, XeF₂ is linear
  • !Confusing the colour of transition metal complexes — mistakes in d-d transition colour predictions
  • !Misidentifying the oxidation state of transition metals in complex ions (especially Fe, Cr, Mn)
  • !Forgetting that s-block elements (alkali and alkaline earth metals) react with water at different rates depending on the period
  • !Confusing the unique properties of fluorine vs other halogens (highest electronegativity, no d-orbitals, forms only −1 oxidation state)

Study tips

  • 1Make a VSEPR geometry table: list molecular formula, electron pairs (bonding + lone pairs), and resulting geometry. NEET tests at least 2 VSEPR problems per year.
  • 2For p-block, use the "top-to-bottom down the group" mnemonic approach: anomalous behaviour of first members (N, O, F) compared to heavier congeners.
  • 3Memorise coordination compound IUPAC names, magnetic properties (number of unpaired d-electrons), and crystal field theory basics (octahedral vs tetrahedral splitting).
  • 4Drill NCERT Inorganic reactions: preparation of SO₂ from Cu + H₂SO₄, production of NO from HNO₃, Ostwald process, Haber process, Contact process.
  • 5For hydrogen bonding, know examples: inter-molecular (H₂O, HF, NH₃) vs intra-molecular (o-nitrophenol, salicylaldehyde). NEET asks about effects on boiling point.
  • 6For NCLEX-RN: the California Board of Registered Nursing requires LiveScan fingerprinting before ATT release; book early because LiveScan vendors fill 2–3 weeks out.
  • 7For MCAT/SAT/ACT: California universities are test-blind for SAT/ACT undergraduate admission as of 2024; verify whether your target medical/grad programs still require MCAT/GRE.
  • 8For CDL: California has its own "California Special Requirements" addendum on top of FMCSA; review the CA Commercial Driver Handbook before sitting the written test.

Sample NEET Chemistry — Inorganic Chemistry questions

These sample items mirror the format and difficulty of real NEET questions. Practice with thousands more on the free Koydo question bank.

  1. 1

    The geometry of XeF₄ according to VSEPR theory is:

    • ATetrahedral
    • BSquare planarCorrect
    • CSee-saw
    • DSquare pyramidal
    Why this answer?

    XeF₄ has 6 electron pairs around Xe: 4 bonding pairs + 2 lone pairs. The electron-pair geometry is octahedral. The two lone pairs occupy axial positions, giving a square planar molecular geometry.

  2. 2

    The number of unpaired electrons in Fe³⁺ in the ground state (outer d-electrons in high-spin) is:

    • A3
    • B4
    • C5Correct
    • D6
    Why this answer?

    Fe³⁺ has the configuration [Ar] 3d⁵. In the high-spin state, Hund's rule places one electron in each of the five 3d orbitals, giving 5 unpaired electrons. This maximum spin state corresponds to the maximum magnetic moment.

  3. 3

    Which of the following does NOT exhibit hydrogen bonding?

    • AH₂O
    • BHF
    • CNH₃
    • DHClCorrect
    Why this answer?

    Hydrogen bonding requires a hydrogen atom bonded to a highly electronegative atom (N, O, or F). HCl involves Cl, which is less electronegative and has a larger atomic radius than F, O, or N — its H is insufficiently positive and Cl insufficiently electronegative for significant hydrogen bonding. H₂O, HF, and NH₃ all exhibit hydrogen bonding.

Frequently asked questions

How much of NCERT is needed for NEET Inorganic Chemistry?
Almost 100% of NEET Inorganic Chemistry questions are answerable from NCERT. This includes in-text examples, exercises, and boxed information. Candidates must read NCERT Class 11 Chapters 3–10 and Class 12 Chapters 6–9 in full, including footnotes.
Is coordination chemistry important for NEET or mainly for JEE?
Coordination chemistry is tested in both NEET and JEE. For NEET, questions focus on nomenclature, coordination number, oxidation state, geometry (octahedral vs square planar vs tetrahedral), and magnetic properties — all covered in NCERT Class 12 Chapter 9. JEE goes deeper into isomerism and stability constants.
What is the NEET pass rate for Californian candidates?
Pass rates for NEET candidates in California, USA are published periodically by the awarding body. Practice questions, full-length simulations, and weak-area drills are the highest-impact way to improve your odds.
How long should Californian candidates study Chemistry — Inorganic Chemistry for the NEET?
For most candidates, focused mastery of Chemistry — Inorganic Chemistry requires 20–40 hours of deliberate practice — drilling sample questions, reviewing failure modes, and timing yourself against exam conditions. California is the largest U.S. testing market for NCLEX, MCAT, SAT, and ACT. The CA Board of Registered Nursing has notoriously long endorsement timelines (8–14 weeks). Combine Chemistry — Inorganic Chemistry study with full-length mock exams in the final two weeks before your test date.
