Definition of Hydrohalogenation

Hydrohalogenation is a chemical process in which there is a breakage of double bonds present in alkenes. This breakage results in the electrophilic attack on one carbon by a hydrogen atom whereas, on the other carbon, a halogen is added. A carbocation is also formed in this type of reaction as an intermediate product.


According to markovnikov’s addition rule, the more substituted carbon would receive the halogen and hydrogen atom will be added to the less substituted carbon. The product of this reaction is known as an alkyl halide. It can also be called haloalkane. An inert solvent is required to carry out such a reaction.
