1. Draw the detailed mechanism for the following acetal formation reaction. Include curved arrows and show all intermediates. Step 1: Formation of a hemiacetal (three steps) (1) proton transfer, (2) nucleophilic attack, and (3) proton transfer Step 2: Formation of an acetal (four steps) (1) proton transfer, (2) loss of a leaving group, (3) nucleophilic attack, and (4) proton transfer
