Consider formation of two sp-sp−hybrid orbitals, one directed toward oxygen and directed 180^o180

o

opposite.

This contains carbon lone pair, leaving empty spsp hybrid orbitals with a filled oxygen \sigmaσ-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:C≡O with a dative bond from oxygen atom to the less electronegative carbon atom.

Answer 2

The valency bond structure of carbon monoxide molecule is:

●Carbon monoxide contains carbon lone pair, leaving empty sp hybrid orbitals with a filled oxygen σ-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≡O with a dative or valence bond from oxygen atom to the less electronegative carbon atom.
