WebA carbocation can be formed only if it has some extra stabilization. For any cation the most stable arrangement of electrons in orbitals results from making filled orbitals as low in … Carbonium ions can be thought of as protonated alkanes. Although alkanes are usually considered inert, under superacid conditions (e.g., HF/SbF5), the C-H sigma bond can act as a donor to H . This results in a species that contains a 3c-2e bond between a carbon and two hydrogen atoms, a type of bonding common in boron chemistry, though relatively uncommon for carbon. As an al…
