Vedclass · Answer

(C) An ambidentate ligand is a ligand that can coordinate to the central metal atom through two different donor atoms.In the complex $[M(en)(SCN)_4]$,the ligand $en$ (ethylenediamine) is a bidentate chelating ligand,which coordinates through two nitrogen atoms.The ligand $SCN^-$ (thiocyanate) is an ambidentate ligand because it can coordinate through either the sulfur atom $(S-CN^-)$ or the nitrogen atom $(N-CS^-)$.There are $4$ $SCN^-$ ligands present in the complex.Therefore,the number of ambidentate ligands in the complex is $4$.

Number of ambidentate ligands in a representative metal complex $[M(en)(SCN)_4]$ is $[en = \text{ethylenediamine}]$
