(a)
Interpretation: The acetal and hemiacetal carbons for maltose are to be labeled.
Concept introduction: Acetals contain two alkoxy groups on a single carbon atom, whereas Hemiacetals contains one alkoxy group and one hydroxyl group attached to same carbon atom.
(b)
Interpretation: The products formed when maltose reacts with [1]
Concept introduction: Glycosidic linkages are hydrolyzed in presence of acid to form cyclic hemiacetal and corresponding alcohol. Acetals in the presence of acid undergo hydrolysis to form cyclic hemiacetals.
(c)
Interpretation: The products formed when the compound formed in the third reaction of part (b) is treated with aqueous acid are to be drawn.
