Question

Here how many ligands are ambidentate?

$\text{CN}^{-} \text{,} \, \text{ONO}^{-} \text{,} \, \text{S}_{\text{2}} \text{O}_{\text{3}}^{\text{2} -} \text{,} \, \text{CNO}^{-} \text{,} \, \text{C}_{\text{2}} \text{O}_{\text{4}}^{\text{2} -} \text{,} \, \text{CH}_{\text{3}} \text{COO}^{-} \, \text{en}$

Answer 1

Here $\text{CN}^{-} \text{,} \, \text{ONO}^{-} \text{,} \, \text{S}_{\text{2}} \text{O}_{\text{3}}^{\text{2} -} \text{,} \, \text{CNO}^{-}$ are ambidentate ligands.
