Question

Define homologous series? give it's characteristics

Answer 1

Answer:

ans ...

Explanation:

In organic chemistry, a homologous series is a series of compounds with the same functional group and similar chemical properties in which the members of the series differ by the number of repeating units they contain. ... They share common characteristics: They all contain the same functional group.

.....I hope it is helpful

Answer 2

Homologous Series:

A series of similarly constituted compounds in which the members present have the same functional group and similar chemical properties and any two successive members in a particular series differ in their molecular formula by CH2 unit is called a Homologous Series.

Properties Of a Homologous Series:

• All the members of a Homologous Series can be represented by the same general formula.

• Any two adjacent homologous differ by 1 carbon atom and 2 hydrogen atoms in their molecular formula.

• With increase in the molecular mass, the gradual change in the physical properties occurs.

• The difference in the molecular masses of any two adjacent homologous is 14 u.

• E.g. CH4, C2H2 etc.
