Question

Supplementary SESSION WII UE CU UN 2/11/20 0 1) In each of the following nucleophilic addition reactions (i) using arrows provide a mechanistic explanation of the course of the reaction (show intermediates); (ii) write the product of the reaction. (32 points) a. Show the mechanism of acetal formation through hemiacetal reacting butanone with (RS)-2,3- butanediol under acidic catalysis. The acetal formation reaction from hemiacetal is the intramolecular reaction. (6 points = 3 points for hemiacetal + 3 points for acetal)
