WebAboutTranscript. The bromination of benzene is an example of an electrophilic aromatic substitution reaction. In this reaction, the electrophile (bromine) forms a sigma bond to the benzene ring, yielding an intermediate. Then, a proton is removed from the intermediate to form a substituted benzene ring. Created by Sal Khan. WebThe Mechanism for the Bromination Reaction. Steps involved in the progression of these reactions are as follows: The electrophile is activated using a Lewis acid. The activated electrophile then attacks benzene. To restore the aromatic ring, deprotonation takes place. Formation of the Electrophile: Benzene is a weak nucleophile, whereas Bromine ... gâteau ananas weight watchers
