The contrasting behavior of benzene and anthracene in the through 蟺-system passing of a (+) charge is examined by considering para-diethynylbenzene and para-diethynylanthracene spacers. The (de)localization of their bonds in both neutral and cationic forms are compared by a two-electron population anal.; the electron-pair distributions are calculated in orbital spaces appropriate for population anal., as the natural AOs, in which two-electron correlations are also studied. When the spacer involves benzene, then its oxidation causes a reorganization of electron pairs towards a pronounced quinoid bond (de)localization, which induces analogous bond deformations; on the contrary, in the case of anthracene, a similar quinoid (de)localization (and the corresponding bond deformation) is impeded, due to the possibility of addnl. delocalization on its central ring. As shown, these electron-pair reorganizations are the driving force for the corresponding geometrical deformations.
