Halogen addition reaction

A halogen addition reaction is a simple organic reaction where a halogen molecule is added to the carbon–carbon double bond of an alkene functional group.

The general chemical formula of the halogen addition reaction is:

C=C + X2 → X−C−C−X

(X represents the halogens bromine or chlorine, and in this case, a solvent could be CH2Cl2 or CCl4). The product is a vicinal dihalide.

This type of reaction is a halogenation and an electrophilic addition.
