Question

What happened with bond order of C to o when metal make complex with carbonyl​

Answer 1

Answer:

The carbonyl carbon atom shares two of its four valence electrons with the carbonyl oxygen atom, and its remaining two electrons form two single bonds to other atoms.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. A pair of bonds arises from overlap of filled d-orbitals on the metal with a pair of -antibonding orbitals projecting from the carbon atom of the CO.
