Define homologous series of carbon compound: Mention any two characteristics of homologous series.

Homologous series: The series of carbon compounds in which two successive compounds differ by –CH₂ unit is called homologue series.

Example:

● CH₄, C₂H₆, C₃H₈…..

● CH₃OH, C₂H₅OH, C₃H₇OH….

Characteristics

i. They have one general formula.

ii. Each compounds in the series differs by –CH₂ group.

iii. They have similar chemical properties due to the same functional group.
