Which drawing represents a σ^* antibonding molecular orbital for a homonuclear diatomic molecule?

Question

Quizplus · Accepted Answer

Option B shows two lobes with opposite phases, which represents an antibonding molecular orbital. The superscripts indicate the number of electrons in each orbital, and the subscripts indicate the orbital's energy level. The orbitals in option B have one electron in the sigma-star orbital (σ*) and zero electrons in the sigma orbital (σ).
