A theoretical study of the structures, energetics, stabilities, reactivities, and out-of-plane distortive tendencies of skeletally substituted benzenes (CH) (sub)5 XH and (CH) (sub)4 (XH) (sub)2 (X= B (super)-, N (super)+, Al (super)-, Si, P (super)+, Ga (super)-, Ge, and As (super)+)

Research has been conducted on the mono-(CH) (sub)5 XH and skeletally substituted (CH) (sub)4 (XH) (sub)2 benzenes. The molecular orbital theory and the hybrid density functional theory calculations used in investigating these compounds and the computed relative energies of the disubstituted isomers are discussed.
