(a) Describe the changes in bonding that would occur in benzene if two electrons were removed from the HOMO (highest occupied molecular orbital). This removal would correspond to an oxidation of benzene to C₆H₆²⁺.

(b) Describe the changes in bonding that would occur if two electrons were added to the LUMO (lowest unoccupied molecular orbital). This addition would correspond to a reduction of benzene by adding two electrons to give C₆H₆^2–. Do you expect these ions to be diamagnetic or paramagnetic?
