10.8.1. Anti-Markovnikov addition of HBr to alkenes We saw in section 10.4 that under normal conditions, HBr adds to an unsymmetrical alkene to form an alkyl halide where the H goes onto the less substituted carbon, and the Br goes onto the more substituted carbon – thus, it obeys Markovnikov’s Rule. However, when heated in the presence of a dialkyl peroxide (often written as ROOR), a

Syn or anti addition

In anti addition, two substituents are added to opposite sides (or faces) of a double bond or triple bond, once again resulting in a decrease in bond order but an increase in number of substituents. The classical example of this is bromination (any halogenation) of alkenes. Aldol synthesis gives rise to stereocenters in the molecule.
