Question

Quizplus · Accepted Answer

Benzene has six carbon atoms, and in the molecular orbital theory, these six atoms form a delocalized pi system. This system consists of six pi electrons that occupy the pi bonding molecular orbitals. In addition, the pi antibonding molecular orbitals are also formed, and they are labeled as π*1, π*2, and π*3. Each pi antibonding molecular orbital can accommodate two electrons that are antibonding in nature. Therefore, benzene has three pi antibonding molecular orbitals.
