Vedclass · Answer

(D) In $Fe(CO)_5$,the $Fe-C$ bond is formed by the donation of a lone pair of electrons from the $CO$ ligand to the $Fe$ atom,which forms a $\sigma$ bond. Additionally,there is $d\pi-p\pi$ back-bonding where electrons from the filled $d$-orbitals of $Fe$ are donated into the empty antibonding $\pi^*$ orbitals of the $CO$ ligand,which forms a $\pi$ bond. Therefore,the $Fe-C$ bond possesses both $\sigma$ and $\pi$ character.
