Question

What is Homologous Series ? Write any five properties of it

Answer 1

Hey mate !

A series of a organic compound each containing a characteristic functional group and the successive members differ by from each other in molecular formula by --CH2--(methylene) group is called homologous series.

Characteristics / Properties of Homologous series :-

1. It can be represented by the same general formula.

2. It have the same functional group.

3. The successive members differ in their molecular formula by --CH2-- group, they differ in molecular weight by 14 units.

4. It can be prepared by similar chemical methods.

5. They show similar chemical properties.

6. They show graduation in physical properties such as melting point, boiling point, density or solubility.


Hope it's help you!
This answer had already written in 10th class board exam ^_^

mark as a brainlist!

Answer 2

A Homologous series is a series of compounds with similar functional groups. The Homologous series have similar functionalities.

The five properties of the Homologous series are:

• They have a repeating unit as they proceed. The repeating unit of an alkaline group is $CH_{2}$.
• The functional groups define the properties of the compound.
• The repeating unit can occur any number of times.
• The physical properties such as density, boiling point, the melting point of the members of a homologous series increase with a rise in molecular mass.
• The individual members of this series are prepared by the general method of preparation.
