QUESTION :
To write the molecule formula of first 2nd and 3rd member of homologous series of Ethane.
ANSWER :
Defination of Homologous series :
A Homologous series is a group of organic compounds having similar structure and similar chemical properties in which the successive compounds differ by CH2 group.
◆ Ethane have single C - C bond ,so it comes under Alkanes.
If Ethane is the first member of the homologous series then the 2nd and 3rd members are :
1st member : Ethane -->[ C2H6 ]
So,
2nd member : Propane --> [ C3H8]
3rd member : Butane --> [ C4H10]
