Define Isomers and Isomerism. How many types of Isomerism are ? Explain.

Isomers and Isomerism

Compounds which have same molecular but different structural formulae are called isomers and the phenomenon is known as isomerism.

1. Chain Isomerism – The isomerism in which the isomers differ from each other due to the presence of different carbon chain skeletons .Example: n-butane and iso-butane.

2. Position Isomerism – the type of isomerism in which the isomers differ in the position of the functional group. Example: But-1-ene and But-2-ene.

3. Functional Isomerism – The type of isomerism in which the isomers differ in structure due to the presence of different functional groups.
