Question

Find the number of ligand(s) which is/are non-classical ligand.
$C O, N O, C_{2} H_{4}, C$ $_{3}$ H $_{5}^{-}$ , $H^{-}$

Solution

The number of ligand(s) which is/are non-classical ligand is 4. These include CO, NO, C $_{2}$ H $_{4}$ , C $_{3}$ H $_{5}^{-}$ .
They are pi bonding ligands.
They form complexes only with transition metals by simultaneous donor and acceptor interaction between occupied and free orbitals of the pi ligand and the d orbitals of the metal.
