Question

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> In which of the following pairs, both the ligands are ambidentate in nature:

• A. $C{N}^{-},N{O}_2^{-}$
• B. $N{H}_3,SCN$
• C. $N_3^{-},N{O}_2^{-}$
• D. $NC{S}^{-},C_2{O}_4^{2-}$

Answer 1

The correct option is A $C{N}^{-},N{O}_2^{-}$

Ambidentate ligand is a type of ligand which can attach to the central metal atom through atoms of two different elements. More specifically ambidentate ligands have more than one donor atom but during coordinate bond formation only one of them attaches itself to the central metal atom.
So, $C{N}^{-},N{O}_2^{-}$ are ambidentate ligands.
