Question Question 6
What is a homologous series? Explain with an example.
A homologous series is a group of organic compounds having a similar structure and similar chemical properties in which the successive compounds differ by a CH2 group.
For example,
Ethene [C3H6], Butene [C4H8], Propene [C5H10] etc., are part of the alkene homologous series.
They differ by a -CH2- unit.
The general formula of this series is CnH2n where n = 2, 3, 4 etc.
