Question

What is homologous series???

Answer 1

$\underline{ \bold \red{Homologous \: Series - }}$A series is a family or class of structurally similar organic compounds containing the same functional group and in which two successive members differ by CH2 is called homologous series.

➡️The members of a homologous series are called homologoues.

Characteristics of Homologous series :-

1. All the members are of a homologous series can be represented by same general formula.

2. The molecular mass of two successive members of a homologous series differ by 14.

3. Each successive member differs in a formula by a common difference of CH2.

4. All the members of a particular homologous series show almost same chemical properties because of the presence of the same functional group.

5. All the members of a particular homologous series can be prepared by the same general methods of preparation.

Answer 2

Answer:

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.

For example: Methane, Propane
