In the electronic structure of the carbonyl group, what is the hybridization state of the oxygen atom according to valence bond theory?
Q1. In the electronic structure of the carbonyl group, what is the hybridization state of the oxygen atom according to valence bond theory?
Answer: sp2
Explanation: Both carbon and oxygen in the carbonyl group are sp2 hybridized to facilitate the double bond. Option A is incorrect as sp3 implies single bonds.
