Class 12 Chemistry — Chapter 5: Coordination Compounds
96 practice questions · 32 Easy · 32 Medium · 32 Hard
Practise Class 12 Chemistry Chapter 5, "Coordination Compounds", with 96 NCERT-aligned multiple-choice questions. The set is split into 32 Easy, 32 Medium and 32 Hard questions, so you can warm up on the fundamentals and then push into the exam-level problems that separate top scorers in CBSE Board exams, JEE Main, JEE Advanced and NEET UG.
"Coordination Compounds" is one of the chapters where reactions, named concepts, and balanced numerical work really pays off. Each MCQ on this chapter is timed and uses exam-grade marking (+2 correct, −1 wrong, 0 skipped), training the same accuracy-under-pressure that real papers demand. Every question carries a short explanation, so a wrong answer becomes a quick lesson rather than a dead end — the fastest way to close gaps before a test.
Use this chapter as targeted revision: attempt the Easy set first to confirm your basics on Coordination Compounds, then move to Medium and Hard to test application and problem-solving. Your accuracy, streaks and XP save automatically, and the chapter feeds into your overall Class 12 Chemistry mastery score. A few sample questions are shown below; sign in free to practise all 96.
Key concepts: Coordination Compounds (Class 12 Chemistry)
This chapter covers coordination compounds — Werner's theory, nomenclature, isomerism, and bonding via Valence Bond and Crystal Field theories.
- Werner's theory
- Metals show primary (ionisable) and secondary (fixed, = coordination number) valencies; ligands satisfy the secondary valency.
- Ligands & coordination number
- Ligands are electron-pair donors (mono-, bi-, polydentate); the coordination number is the number of donor atoms bonded to the metal.
- Isomerism
- Structural (ionisation, linkage, coordination) and stereoisomerism (geometrical cis–trans, optical) occur in complexes.
- Valence Bond Theory
- Explains shape and magnetism via hybridisation (e.g. d²sp³ octahedral); predicts inner/outer-orbital complexes.
- Crystal Field Theory
- Ligands split the d-orbitals (Δ₀); strong-field ligands give low-spin, weak-field give high-spin complexes — explaining colour and magnetism.
Key formulas — Coordination Compounds
💡 Exam tips for Coordination Compounds
- Strong-field ligands (large Δ₀) favour low-spin (fewer unpaired electrons); weak-field favour high-spin.
- Learn the spectrochemical series order to predict crystal-field splitting and colour.

Δ_o is the splitting parameter.
