(a)
Interpretation:
The acetal carbon atom in the given structure has to be identified.
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.
Acetal is formed when the formed hemiacetal reacts with further alcohol molecule so that the hydroxyl group in the hemiacetal is converted into alkoxy group. This can be shown as given below,
Acetal contains two alkoxy groups substituted on the same carbon atom. This carbon atom is known as acetal carbon atom.
(b)
Interpretation:
The acetal carbon atom in the given structure has to be identified.
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.
Aldehydes and ketones react with alcohol to form hemiacetal as the product. This reacts with further molecule of aldehyde or ketone to form acetal.
Acetal is formed when the formed hemiacetal reacts with further alcohol molecule so that the hydroxyl group in the hemiacetal is converted into alkoxy group. This can be shown as given below,
Acetal contains two alkoxy groups substituted on the same carbon atom. This carbon atom is known as acetal carbon atom.
