In the structure below, the sigma bond of the carbonyl is formed from the overlap of a(n) ________ atomic orbital of carbon and a(n) ________ atomic orbital of oxygen.

Question

Quizplus · Accepted Answer

In a carbonyl group, the sigma bond is formed by the overlap of the carbon atom's sp2 hybridized atomic orbital and the oxygen atom's sp2 hybridized atomic orbital. Therefore, the correct answer is C, which lists the correct hybridization and atomic orbitals involved in the sigma bond formation. Choices A and D are incorrect because they refer to the wrong hybridization or atomic orbitals that are not involved in carbonyl sigma bond formation.
