They have the same molecular formula, but belong to different homologous series.

Explanation:

Functional group isomerism is an example of structural isomerism – where a molecule has the same molecular formula, but a different arrangement of atoms in space.

In functional group isomerism, the atoms are arranged as such that the isomers belong to different families (homologous series ) of molecules.

Acetone and propionaldehyde are examples of functional group isomers, because they have the same molecular formula #C_3H_6O# but belong to different homologous series.

Acetone is a ketone
