(a)
Interpretation:
The given structure has to be classified as an aldehyde, a ketone or neither.
Concept Introduction:
Carbonyl groups are the one which contain a double bond between carbon and oxygen atom.
An aldehyde is a carbonyl compound in which the carbonyl carbon atom is bonded to at least one hydrogen atom directly. The other group attached to the carbonyl carbon atom can be alkyl, cycloalkyl, or aryl group.
A ketone is a carbonyl compound in which the carbonyl carbon atom is bonded to two other carbon atoms directly. The groups attached to the carbonyl carbon atom can be alkyl, cycloalkyl, or aryl group.
(b)
Interpretation:
The given structure has to be classified as an aldehyde, a ketone or neither.
Concept Introduction:
Carbonyl groups are the one which contain a double bond between carbon and oxygen atom. Aldehydes and ketones possess this carbonyl functional group in it. The structural representation of a carbonyl group can be given as shown below,
