Explain isomerism. State any four characteristics of isomers. Draw the structures of possible isomers of butane, C4H10.

Solution
Isomerism, is a phenomenon shown by chemical compounds, due to which two or more compounds with similar molecular formula occur in nature but have different physical and chemical properties. Such compounds are called isomers.

Isomers have, following characteristics :

1. Same molecular formula but different structural formulas.
2.Two isomers can have different boiling points.
3. Isomers can have different functional groups.
4.Isomers have same no. of atoms.
