WebFeb 13, 2024 · A carbocation is an ion with a positively-charged carbon atom. A carbocation is very electron-poor, and thus anything which donates electron density to the center of electron poverty will help to stabilize it. Conversely, a carbocation will be destabilized by an electron withdrawing group. WebSep 16, 2024 · What is shown in Figure 1.21 as the specific interaction of methyl group fragment orbitals with a carbocation center can easily be adapted to other situations, where alkyl groups attach to π-systems through simply replacing the C(2p z) orbital with the appropriate vacant π-MOs.
WebJun 3, 2024 · The Tricyclopropyl methyl carbocation is greatly benefited by angle strain. The bent bond effect greatly stabilizes the cation by providing a large pseudo – pi system that involves the electrons of the “bent bonds” of the cyclopropyl rings. Conversely, the Triphenyl methyl carbocation suffers form steric strain. The large phenyl rings ...
