Concept introduction: Electrophilic addition reactions are those in which breaking of pi bond take place to form new sigma bond.
The addition of Halogens to alkenes is a stereospecific reaction. The resultant product is meso compound, if alkene is cis and addition of halogen is syn addition. If addition of halogen is anti, then the resultant products are racemic mixture. In case of trans alkene, the resultant product is meso, if addition of halogen is anti. The resultant products are racemic mixture, if the addition of halogen is syn.
