Concept:An ambident ligand is one that contains two different donor atoms, but attaches to the central metal ion through only one of them at a time.Explanation:In $\mathrm{SCN}^{-}$, the two possible donor atoms are sulfur and nitrogen.It can coordinate as $\mathrm{M}-\mathrm{SCN}$ through sulfur, or as $\mathrm{M}-\mathrm{NCS}$ through nitrogen.Hence, $\mathrm{SCN}^{-}$ is an ambident ligand.Ethylene diamine is a bidentate ligand with two nitrogen donor atoms of the same type.$\mathrm{Cl}^{-}$ is a monodentate ligand.EDTA is a hexadentate ligand.None of these show two different donor atoms, so they are not ambident.Answer:Option D: $\mathrm{SCN}^{-}$
