WebHydrohalogenation Mechanism. Step 1: The pi electrons of the alkene attack a hydrogen of HBr resulting in the formation of a carbocation and a bromide ion. The carbocation is a high energy intermediate making this the rate determining step (slow step) of the reaction. Step 2: When there is no favorable rearrangement the bromide ion carries out ...
