Question

give two characteristics of homoogus series

Answer 1

Homologous series is defined as a systematic order of organic compounds having same functional group that can be represented by same general formula and prepared by same method. The difference between two consecutive members in their composition is –CH2unit.

Each member of a homologous series is known as homologue and this phenomenon is called homology.

Characteristics of homologous series:

1.    The members of a series have same functional group.


2.    Two consecutive members of a homologous series differs each other in their composition by –CH2unit.

Example:

Alcohol (-OH)

CH3-OH , CH3-CH2-OH , CH3-CH2-CH2-OH

Answer 2

#The members of a particularhomologous series have almost same chemical properties due to presence of same functional group.

#Neighbouring members differing by CH2.
