There are several ways to halogenate Alkenes. The simplest is by adding appropriate hydrogen halides, where the reaction follows Markovnikov's rule. This rule states that the halogen will become bonded to the more highly substituted carbon. This is a result of greater carbocation stability of more highly substituted carbon atoms, which have more ability to distribute the positive charge to the attached alkyl groups. When both carbon atoms have the same number of substituents, a mixture of products will often result.
