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
