What is the IUPAC name?

IUPAC Nomenclature:

IUPAC stands for International Union of Pure Applied Chemistry. This organization developed a standard way to name organic molecules. The longest carbon chain of the organic molecule is named based on the number of carbons using the following prefixes:

1C -meth

2C - eth

3C - pro

4C - but

5C - pent

6C - hex

7C - hept

The ending of the name indicates if the molecule contains a functional group. Substituents are also named using the prefixes and a number tells which carbon of the main chain they are attached to.
