5. The following questions relate to the reaction below: a. Draw the mechanism for the reaction: b. Using your mechanism explain how the identity of the best lesving group is altered. c. Fill out the synthesis below with the missing products/reagents d. Assume that this reaction is part of the synthesis that requires reduction of the alkere to the alkane. Explain why the acetal formation needs to happen first including what would happen if the acetal and alkene reduction reaction order was reversed
