Accoding to the polygon rule, how many nonbonding nolecular orbitals are present in benzen?

Options

A. Zero
B. Three
C. Six
D. Four

Answer

1

Explanation

For benzene, the polygon is a regular hexagon inscribed in a circle with one vertex at the bottom of the circle. The vertices represent the relative energies of the molecular orbitals with energies increasing from the bottom to the top of the circle. The vertices below the horizontal diameter are bonding `pi`'s Those above are antibonding `pi`'s and those on the diameter are nonbinding `pi^(n)`
