Quizplus · Accepted Answer

Benzene has a six-membered ring with 6π electrons, which are distributed over the ring in a delocalized π molecular orbital system. This gives rise to three π bonding molecular orbitals and three π antibonding molecular orbitals. Therefore, there are six π molecular orbitals in total, with three bonding and three antibonding.
