Question

The valence bond structure of carbon monoxide is best described as $:C\equiv O$ with a dative bond from oxygen atom to the less electronegative carbon atom.
If true enter 1 else 0.

Answer 1

The electronic configuration of $C$ is $1s^{2}2s^{2}2p^2.$.
Consider formation of two $sp-$hybrid orbitals, one directed toward oxygen and directed ${180}^o$ opposite.
This contains carbon lone pair, leaving empty $sp$ hybrid orbitals with a filled oxygen $\sigma$-orbital.
To complete the octet, C forms a pi bond and a dative bond.
Hence, the valence bond structure of carbon monoxide is best described as $:C\equiv O$ with a dative bond from oxygen atom to the less electronegative carbon atom.
