Question

Which one, if any, of the following statements about the MO treatment of the bonding in benzene is correct?

a. Benzene has no pi electrons.
b. Benzene is a nonaromatic compound.
c. Benzene's MO diagram includes three pi bonds and one sigma bond.
d. Benzene's MO diagram includes six pi bonds.

Answer 1

The correct statement about the MO treatment of the bonding in benzene is that its MO diagram includes three pi bonds and one sigma bond.

Step-by-step explanation:

The correct statement about the MO treatment of the bonding in benzene is option c. Benzene's MO diagram includes three pi bonds and one sigma bond. In benzene, the true bonding between carbon atoms is a hybrid of a single and double bond, resulting in three pi bonds and one sigma bond. The pi bonding electrons are free to move completely around the ring, indicating delocalization of electrons in benzene.
