Coordination Compounds
Test your knowledge of coordination compounds for JEE Main — Werner's theory, the spectrochemical series, and how ligand field strength changes geometry and magnetism.
Fifteen questions cover the classic Ni(CO)₄/NiCl₄²⁻/Ni(CN)₄²⁻ comparison, linkage and ionization isomerism, optical isomerism, and the chelate effect.
Anchored in the exact comparisons JEE Main uses to test whether you understand ligand field theory, not just memorized formulas.
