• IUPAC(International Union of Pure and Applied Chemistry ) is a method of nomenclature of organic chemical compounds of organic chemistry.

Method of nomenclature-

• 1-Identify the parent hydrocarbon chain which must have maximum number of multiple  and single bonds,should have the maximum lengths.
• 2-Identify the parental functional group.
• 3- Identify the  side chain that are branched chain
• 4-Now identify the  remaining functional group and if any present name them with their ionic  prefixes.
