(a)
Interpretation:
The given compound is a hemiacetal or not has to be indicated.
Concept Introduction:
Aldehydes and ketones react with alcohol to form hemiacetal as the product. This reacts with further molecule of aldehyde or ketone to form acetal.
Hemiacetal is a addition product that is obtained by reaction between aldehyde or ketone with alcohol. The general reaction of hemiacetal formation can be given as,
From the above general structure of hemiacetal it is found that it is an organic compound that contains a carbon atom that is bonded to an alkoxy group and a hydroxyl group.
(b)
Interpretation:
The given compound is a hemiacetal or not has to be indicated.
Concept Introduction:
Aldehydes contain a carbonyl group that is bonded to a hydrogen atom and a carbon atom. Ketones are compounds that contain a carbonyl group bonded to two carbon atoms. Aldehydes and ketones undergo addition reaction across the carbonyl group.
