Which of the following give good synergic bond with metal?
1 $\mathrm{CO}$
2 $\mathrm{NH}_{3}$
3 $\mathrm{H}_{2} \mathrm{O}$
4 $\mathrm{Cl}^{-}$
Explanation:
(A) : Synergic bonding is also known as backbonding generally ligand donate lone pair into the vacant orbital of metal. But in case of synergic bond ligand to metal donation occur as well as donation of lone pair from filled orbital of metal to vacant orbital of ligand is occurred. CO ligand give good synergic bonding among the following.

$\mathrm{CO}$ is a stronger ligand than $\mathrm{Cl}^{-}$, because
1 $\mathrm{CO}$ is neutral molecule
2 $\mathrm{CO}$ has $\pi$ bonds
3 $\mathrm{CO}$ is poisonous
4 $\mathrm{CO}$ is more reactive
Explanation:
(B) : According to spectrochemical series, $\mathrm{CO}$ is strongest ligand than $\mathrm{Cl}^{-}$because $\mathrm{CO}$ forms both $\sigma$ and $\pi$ bond due to synergic effect.
