Question

What is meant by Isomers? Draw the structure of two isomers of butane, C4H10. Explain why we cannot have isomers of first three members of alkane series.

Answer 1

I. isobutane
compounds having same molecular formula but different structural formula
ii butane
CH3- CH2- CH2- CH3

because of following laws of isomers
I. parent chain should have most no. of carbon atoms
ii. branching cannot be done from first or last carbon atom
(parent chain is the basic chain from which branching is to be done)
