Nomenclature of alcohols

According to IUPAC nomenclature alcohols are named by replacing ‘e’ in the name of parent alkane by ‘ol’.

In this system following rules are followed:

1. The longest continuous chain containing the carbon bonded to OH group is selected as the parent chain.
2. The carbon atoms in the chain are numbered in such a way that the carbon atom carrying the hydroxyl group gets the lowest number. For example,

Serial No.	Name	Structural Formula
1.	Ethan-1-ol
2.	Propan-1-ol
3.	Propan-2-ol
4.	Butan-1-ol
5.	Butan-2-ol
6.	Pentan-1-ol
7.	Pentan-2-ol
8.	Pentan-3-ol
