Vedclass · Answer

(B) In the carbonyl group $(>C=O)$,the carbon atom is bonded to three atoms (one oxygen via a double bond and two other groups/atoms via single bonds) and has no lone pairs. According to the valence bond theory,the carbon atom undergoes $sp^2$ hybridisation to form three $sp^2$ hybrid orbitals. Therefore,the carbon atom of the carbonyl group is $sp^2$ hybridised.
