Part M_1: Mechanism of Electrophilic Aromatic Substitution    10 points


The reaction of  bromine with benzene in the presence of Iron III chloride (FeBr3) catalyst involves three steps. First the catalyst reacts with the bromine to polarize the molecule. Then the mechanism occurs in two more steps of which the first is a slow step followed by a fast step

Initial Step with catalyst:








Step 1-Slow









Step 2-fast
