Which of the following pairs of compounds belongs to the same homologous series?
Answer Details
C2H6 and C4H10 belong to the same homologous series, which is the series of alkanes. The homologous series refers to a group of organic compounds that have similar structures and chemical properties, and the same functional group. They have a general formula, with the same difference in the number of carbon and hydrogen atoms between consecutive members. The alkanes are a homologous series of hydrocarbons with the general formula CnH2n+2. Therefore, C2H6 and C4H10 have different numbers of carbon atoms, but they both have only single bonds between the carbon atoms and hydrogen atoms.
