Concept explainers
(a)
Interpretation:
The hemiacetal carbon in the given compound should be determined.
Concept introduction:
Hemiacetal carbon is a carbon that is bonded to alkoxy and alcohol groups. Hemiacetal forms when an

Interpretation:
The hydroxyl aldehyde that will form the given hemiacetal in a cyclization reaction should be determined.
Concept introduction:
When an aldehyde/
(c)
Interpretation:
The product formed should be determined if the given molecule (B) is reacted with H2SO4and CH3CH2OH.
Concept introduction:
The given molecule is a cyclic hemiacetal. Therefore, when it reacts with an alcohol in the presence of acid, an acetal is formed.
