प्रश्न
Propane and ethane are ______.
पर्याय
Homologues
isomers
उत्तर
Propane and ethane are homologues.
Explanation:
Propane (\[\ce{C3H8}\]) and Ethane (\[\ce{C2H6}\]) belong to the same homologous series of alkanes because they differ by a \[\ce{CH2}\] (methylene) group and follow the general formula \[\ce{C_nH_{2n+2}}\] for alkanes. They are not isomers as they have different molecular formulas.
