Addition of HX to an alkene
The addition of HX to an alkene, hydrohalogenation, is an organic reaction in chemistry wherein hydrogen halide, HX, (that is, a halogen sigma bonded to a hydrogen atom) adds to the carbon-carbon double bond of an alkene following Markovnikov's rule (Markovnikov's rule is observed).
The general chemical formula of the reaction is as follows:
- C=C + HX → H-C-C-X
