$NH_2^-$

Vedclass · Answer

(D) Synergic bonding occurs in ligands that have vacant $\pi^*$ antibonding orbitals capable of accepting electron density from the filled $d$-orbitals of the central metal atom (back-bonding).$CO$,$NO$,and $PPh_3$ possess vacant $\pi^*$ orbitals and are known to form metal-ligand $\pi$-back bonds.$NH_2^-$ is a strong $\sigma$-donor ligand but lacks vacant $\pi^*$ orbitals,therefore it cannot participate in synergic bonding.Thus,the correct option is $D$.

Which of the following ligands does not show synergic bonding with a central metal atom?
