What is the chemical name for isopropyl alcohol?

Isopropyl alcohol, commonly known as rubbing alcohol, has the chemical formula C3H8O. Its systematic name is derived from its structure, specifically indicating the positioning of the hydroxyl (-OH) group. In the case of isopropyl alcohol, this hydroxy group is attached to the second carbon of the three-carbon chain, making it 2-propanol.

In the name "2-propanol," the "2" refers to the location of the hydroxyl group on the carbon chain, while "propanol" indicates that there are three carbons in total (prop- meaning three). This naming convention is consistent with the IUPAC norms for naming alcohols, which dictate that the position of the hydroxyl group should be specified.

This chemical name reflects both its molecular structure and functional group, helping chemists and researchers to easily understand its properties and behaviors in various chemical reactions and applications.
