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.

(with the same general formula, usually varying by a single parameter such as the length of a carbon chain.) Example: alkanes (paraffins).

Answer 2

Explanation:

In organic chemistry, a homologous series is a sequence of compounds with the same functional group and similar chemical properties in which the members of the series can be branched or unbranched, or differ by -CH2.
