Which of the following steps would you expect to occur in the addition reaction mechanism?
I.electrophilic attack on the unsaturated bond
II.formation of carboanion
III.formation of carbocation
IV.nucleophilic attack on the carbocation
V.elimination of a base

Question

The addition reaction mechanism involves the addition of an electrophile to the pi bond of the unsaturated compound, resulting in the formation of a carbocation intermediate. The carbocation can then be attacked by a nucleophile, leading to the formation of the final product. Therefore, the expected steps in the addition reaction mechanism are I (electrophilic attack on the unsaturated bond), III (formation of carbocation), and IV (nucleophilic attack on the carbocation). The other two steps, II (formation of carboanion) and V (elimination of a base), are not typically involved in this type of reaction. Therefore, option A, which includes steps I, III, and IV, is the best choice.
