Questions 3 and 4 refer to the following reaction. The most likely mechanism for this reaction is E2. Briefly explain your answer to question 3. This is an elimination reaction, so the mechanism choices are E1 and E2. Of these, we consider E2 first because it avoids the energetically-expensive process of carbocation formation.
Chloride is a modest leaving group.
Therefore E2 is the most likely mechanism for this reaction. Questions 5 and 6 refer to the following reaction. Circle the major product of this reaction. The major product of this reaction is acetone, 6. Circle the major product of this reaction.
