The solid formed during in-situ generation of bromine from addition of concentrated HBr should be identified. Concept introduction: Alkenes are considered electron-rich and undergo bromination addition reaction with Br 2 in presence of CCl 4 by electrophilic addition reaction. The mechanism of Br 2 addition occurs in two steps. In the first step, nucleophilic olefin abstracts the electrophilic bromine atom from Br 2 and this results in attack of Br + on the electron-rich olefinic bond that forms a sigma bond to each end of the olefinic bond. Such interaction leads to a three-membered bromonium ion intermediate. In the second step, the strained bromonium ion intermediate opens while Br − attack from behind the electron-deficient carbon analogous to S N 2 attack.Reaction of Br 2 addition is highly stereospecific since the dibromo product is always formed by anti-addition.
