Question
An aldehyde as well as a ketone can be represented by the same molecular formula, say $C _3 H _2 O$. Write their structure and them. State the relation between the two in the language of science.
✓

Answer

Since the molecular formula is same for both aldehyde and ketone. Hence they are isomers (same molecular formula but different structural formula or functional group).
Their chemical name is,
Aldehyde: $CH _3 CH _2 CHO = C _3 H _6 O$ (Propanal)
Ketone: $CH _3 COCH _3= C _3 H _6 O$ (Propanone)
