What is meant by isomers? Draw the structures of two isomers of butane, \[{{\mathbf{C}}_{\mathbf{4}}}{{\mathbf{H}}_{\mathbf{10}}}\]. Explain why we cannot have isomers of first three members of alkane series.

Isomers are compounds which have the same molecular formula but different structures.

Since branching is not possible in first 3 members thus isomers of these first members of alkane series is not possible.
