How is a carbocation formed
WebFormation of the Carbocation The carbocations can be formed by either of the following two fundamental steps: Cleavage of a bond of carbon. Electrophilic addition. Cleavage of … 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…
