According to Markovnikov's rule of the electrophilic addition to an alkene, the electrophile, usually a proton, is more likely to add to the less-substituted carbon in a double bond. This arrangement places the intermediate carbocation on the more-substituted carbon , which stabilizes it with the presence of . In the major product of a reaction following Markovnikov's rule, the . will then end up on the more-substituted carbon in a double bond.
