Question

Why we can't have isomers of first three members of alkane?

Answer 1

Answer:

Explanation:

The first three members of alkaline series are

Methane, Ethane and Propane

Methane has chemical formula CH4 , Ethane ---C2H6 and Propane C3H8

In alkanes, isomers arises when a particular compound can be represented in the form of both long straight chain and branched isomer .

The structure of methane , ethane and Propane shows that they do not have sufficient number of carbon atoms to exist in the form of branched Isomer.

Methane- 

  CH4

Ethane  --- CH3-CH3

Propane --- CH3-CH2-CH3

So first three members of alkanes can be represented by Straight chain not by Branching
