Khan Academy: Bromination of Benzene

This video is a concrete example of electrophilic aromatic substitution. 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.
