Isomerism in Alcohols Preparation and Properties

Isomerism in Alcohols Preparation and Properties

Alcohols exhibit four types of structural isomerism:

→ Chain isomerism : Alcoholš containing four or more carbon atoms exhibit chain isomerism in which the isomers differ in the chain of carbon atoms attached to the hydroxyl group.

For example:

Isomerism in Alcohols Preparation and Properties 1

→ Position isomerism : The alcohols containing three or more carbon atoms exhibit position isomerism in which the isomer differ in the position of hydroxyl group.

For example:

Isomerism in Alcohols Preparation and Properties 2

→ Functional isomerism : Monohydric alcohols containing two or more carbon atoms exhibit functional isomerism in which the isomers differ in the functional group. For example : Ether is functional isomer of alcohol.

Isomerism in Alcohols Preparation and Properties 3

→ Optical isomerism : Monohydric alcohols containing atleast one asymmetric carbon atom (chiral atom) which rotate plane poiar light to right or left are called optical isomers.

For example:
