D. Position Isomerism
- Functional group isomerism occurs when two or more compounds have the same molecular formula but a different functional group. In the case of aldehydes and ketones, they both contain the carbonyl functional group (C=O), but differ in the location of this group in the molecule.
- Aldehydes have the carbonyl group at the end of the carbon chain, while ketones have the carbonyl group located in the middle of the carbon chain. Thus, aldehydes and ketones are functional group isomers of each other.
