KCET 2015 Chemistry Solved Paper

The magnitude of Δ0 depends upon the type of ligands. For examples; strong field ligands have high magnitude of the Δ0 and weak field ligands low magnitude of Δo . Spectro chemical order of the ligands Cl−<H2O<NH3<CN−
Cl− is a weak field ligand, therefore, Δo will be minimum
