Question

WHAT IS A HOMOLOGOUS SERIES OF COMPOUNDS ? LIST ANY TWO CHARACTERISTICS OF A HOMOLOGOUS SERIES.
(class 10 CBSE SAMPLE PAPER 2017-18 SCIENCE)

Answer 1

Solution:

A series of compounds having similar structural formulae, same functional group and hence similar chemical properties are called homologous series of compounds.

Characteristics of homologous series:

1.The members of a homologous series have similar chemical properties.

2. Any two adjacent members of a homologous series differ by a CH2 unit in their molecular formulae.

Answer 2

hey

here is answer

homologous series.

homologous series may be defined as follows

a group of organic compounds containing a particular functional group is termed as homologous series.

a member of. homologous series is called a homologue.

characteristics.

1. all the members of homologous series can be described by a common general formula

2. each member of homologous series differs from its higher and lower neighbouring members by common difference of -CH2

3. all the members of homologous series shows similar chemical properties.

4. physical properties in a homologous series show a regular variation with an increase in molecular mass

hope it helps
