Vedclass · Answer

(B) An ambidentate ligand is a ligand that can coordinate to the central metal atom through two different donor atoms. Examples include $NO_2^{-}$,$CN^{-}$,and $SCN^{-}$.In option $A$,$NO_2^{-}$ and $CN^{-}$ are ambidentate.In option $B$,$C_2O_4^{2-}$ (oxalate) is a bidentate ligand,$H_2O$ is a monodentate ligand,and $SO_4^{2-}$ is a bidentate ligand. None of these are ambidentate.In option $C$,$SCN^{-}$ is ambidentate.In option $D$,$CN^{-}$ and $SCN^{-}$ are ambidentate.Therefore,the set containing no ambidentate ligands is $C_2O_4^{2-}, H_2O, SO_4^{2-}$.

List-$I$ (Complex)	List-$II$ (Primary valency and Secondary valency)
$(A)$ $[Co(en)_2 Cl_2] Cl$	$(I)$ $3, 6$
$(B)$ $[Pt(NH_3)_2 Cl(NO_2)]$	$(II)$ $2, 4$
$(C)$ $Hg[Co(SCN)_4]$	$(III)$ $3, 4$
$(D)$ $[Mg(EDTA)]^{2-}$	$(IV)$ $2, 6$

Identify the set which does not have ambidentate ligand$(s)$.
