Step-by-step solution
Co-ordination compounds absorb a particular wavelength following certain rules. Wavelength of light absorbed ∝ 1 Oxidation state of metal ion ∝ 1 Strength of ligand Ligand field strength - CN - > NH 3 > H 2 O > Cl - List I Coordination entity List II Wavelength of light absorbed in nm A CoCl NH 3 5 2 + I. 535 B Co NH 3 6 3 + II. 475 C Co ( CN ) 6 3 - III. 310 D Cu H 2 O 4 2 + IV. 600
