Question

Explain the bonding in metal carbonyls with the help of a Molecular Orbital

Diagram of CO.​

Answer 1

Explanation:

Carbon monoxide bonds to transition metals using "synergistic π* back-bonding". The bonding has three components, giving rise to a partial triple bond. A sigma bond arises from overlap of the nonbonding (or weakly anti-bonding) sp-hybridized electron pair on carbon with a blend of d-, s-, and p-orbitals on the metal.
