Homologous series : It is a homologous series of organic compound which have similar chemical properties. In which successive member differ in molecular formula by CH_{2} group.

                                Members of homologous series

4th member :               C_{4}H_{9}OH

5th member :                C_{5}H_{11}OH

Physical properties: the physical properties depend on the length of carbon chain.

Chemical properties : It depends on the functional group
