$CO$

Vedclass · Answer

(B) $\pi$-acid ligands (also known as $\pi$-acceptor ligands) are ligands that can accept electron density from the metal atom into their empty $\pi^*$ antibonding orbitals. $CO$ (carbon monoxide) is a classic example of a $\pi$-acid ligand because it possesses empty $\pi^*$ orbitals that can accept electron density from the metal $d$-orbitals via back-bonding. $NH_3$,$F^{-}$,and ethylenediamine are $\sigma$-donor ligands.

Which of the following is a $\pi$-acid ligand?
