Answer
2-ethylhexanal has a branched chain with an aldehyde functional group. It is still an isomer of the original compound since it shares the same molecular formula.

Answer
2-ethylhexan-1-ol has a similar chain but differs in the functional group, having an alcohol. Since this compound has the same number of carbon atoms and a different functional group structure, it is an isomer.
Step 4
D 5-methylheptan-3-one

Answer
5-methylheptan-3-one must be analyzed. It contains a carbon skeleton that has 7 carbons in a chain with a ketone. However, its structure indicates that it has a different molecular formula than the original compound, making it not an isomer.
