Quizplus · Accepted Answer

Compound Z is formed from the reaction between glucose (in the open-chain form) and methanol. The reaction involves the formation of an acetal (hemiacetal intermediate reacts with methanol to give acetal). In the acetal, the anomeric carbon (which is indicated by an asterisk symbol) is bonded to the methoxy group (-OCH3) instead of the hydroxyl group (-OH) in the cyclic glucose structure. Since the -OCH3 group is on the opposite side of the ring (i.e., trans) to the -CH2OH group on the anomeric carbon (as shown in the structure), Compound Z is the beta (b) anomer.
