A mechanism for the reaction given below is to be proposed based on the mechanism of reactions of halogens with alkenes. Concept Introduction: > Halogen adds across a double bond to forma cyclic halonium intermediate. The halide ion left over from the first step can then launch a nucleophilic attack to form a vicinal dihalide. > If the reaction is work out in a polar nucleophilic solvent or another functional group that can act as a nucleophile is present in a suitable position, it may attack the halonium ion instead of the left over halide ion.
