What is homologous series? Explain its properties.
Answers
Answer:
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.
Homologous series :-
A series of compounds in which the same functional group substitutes for a hydrogen in a carbon chain is called homologous series. In this series the adjacent members differ by (-CH2) group. Each member of a homologous series is called homolog.
Properties of Homologous Series:-
• All the members of a homologous series can be represented by a common formula.
• Two successive members are differ by one carbon atom and 2 hydrogen atoms.
• All the members of a homologous series possess similar chemical properties.
• There is a small difference between all the members of a homologous series.
• There is always a differenence of 14a.m.u. in atomic mass of two adjacent homologous.
