The chlorination of benzene can be carried out by allowing benzene to react with Cl₂ in the presence of AlCl₃. Cl₂ and AlCl₃ react to form Cl⁺AlCl₄^–. Sketch the reaction profile for the reaction of benzene and Cl⁺AlCl₄^–. Use the same assumptions as in Exercise 35.

Exercise 35

Sketch the reaction profile for the mechanism depicted in Figure 27-21, by assuming the overall reaction is exothermic. Also, experimental evidence suggests that the activation energy for the first step is greater than the activation energy for the second step. Draw structures for the intermediate and transition states.
