Electrophilic Addition The most common applications of alkene halogenation are chlorination and bromination , which are electrophilic addition . General mechanism of electrophilic addition: carbocation E Br --- Br δ + δ Minor Shifts in Electron Density

A chiral carbon is a carbon atom that is bonded to four different substituents. Two different configurations are possible for a chiral center 1. Rectus (R) 2. Sinister (S) Stereoisomers - Enantiomers are molecules that contain chiral centers and are non- superimposable mirror images. (Mirror Images!) Diastereomers are molecules that do not have a mirror image relationship. (Not Mirror Images!) A meso compound is a molecule that contains chiral centers, but also contains an internal plane of symmetry (having superimposable mirror images). A racemic mixture is a mixture containing equal amounts of a pair of enantiomers (racemates).
