1.	What is meant by isomers? Draw the structures of two isomers of butane, C_(4)H_(10). Explain why are cannot have isomers of first three members of alkane series.
Answer» Solution :Isomers are compounds having the same molecular formula but DIFFERENT STRUCTURES. The two isomers of butane, `C_(4)H_(10)` are: `H-UNDERSET(H)underset(\|)OVERSET(H)overset(\|)C-underset(H)underset(\|)overset(H)overset(\|)C-underset(H)underset(\|)overset(H)overset(\|)C-underset(H)underset(\|)overset(H)overset(\|)C-H` Since branching is not possible, isomers are not possible for the first three members of alkane series.
