What is homologous series state its characteristics
Answers
Answer:
Homologous serious is a group or series of organic compounds each containing a characteristic functional group .
Answer:
.
Characteristics of homologous series are :
(1) Each member of the homologous series can be represented by a general formula.
(2) Homologues have same functional groups and similar chemical properties.
(3) Two successive homologues differ by one-CH_2 (methylene) unit and hence molecular weight of each successive member differs by 14.
(4) All the members of a homologous series can be prepared by similar methods.
(5) Physical properties (like melting point, boiling point, density) of the homologues show a gradual change with increase in the molecular weight of the member. Example : Homologous series of alcohols have general formula C_n H_2n+_1OH.
