Question

explain homologous series in alkanes​

Answer 1

Answer:

Homologous series is a series of compounds with similar chemical properties and some functional group differing from the successive member by CH₂.

Explanation:

The successive members vary from each other by a CH₂ unit. For example in CH₄ and C₂H₆, the difference is -CH₂ unit and the difference between C₂H₆ and C₃H₈   is also -CH₂ unit. So CH₄, C₂H₆, and C₃H₈ are homologs.
