Solution
Propane and ethane are homologues.
Explanation:
Propane (C3H8) and Ethane (C2H6) belong to the same homologous series of alkanes because they differ by a CH2 (methylene) group and follow the general formula CnH2n+2 for alkanes. They are not isomers, as they have different molecular formulas.
