Solution: Chlorobenzene, C6H5Cl, is a key intermediate in the manufacture of dyes and pesticides. It is made by the chlorination of benzene, catalyzed by FeCl3, in this series of steps:(1) Cl2 + FeCl3 ⇌ FeCl5 (or Cl+FeCl4−)(2) C6H6 + Cl+FeCl4− ⇌ C6H6Cl+ + FeCl4−(3) C6H6Cl+ ⇌ C6H5Cl + H+(4) H+ + FeCl4− ⇌ HCl + FeCl3(a) Which of the step(s) is (are) Lewis acid-base reactions?

Problem

Chlorobenzene, C6H5Cl, is a key intermediate in the manufacture of dyes and pesticides. It is made by the chlorination of benzene, catalyzed by FeCl3, in this series of steps:
(1) Cl2 + FeCl3 ⇌ FeCl5 (or Cl+FeCl4)
(2) C6H6 + Cl+FeCl4 ⇌ C6H6Cl+ + FeCl4
(3) C6H6Cl+ ⇌ C6H5Cl + H+
(4) H+ + FeCl4 ⇌ HCl + FeCl3

(a) Which of the step(s) is (are) Lewis acid-base reactions?
