The International Union of Pure and Applied Chemistry (IUPAC) refers to the systematic approach taken for the nomenclature of organic compounds. The IUPAC nomenclature of organic compounds essentially consists of three parts which are stem name, prefix, and suffix.
Firstly we have to locate the longest carbon chain in our compound.
In the second step, name that longest carbon chain.
In the third step, determine the ending in a given compound. For example, if there is a functional group in your compound, you need to find the suffix that goes with it and put it at the end of your compound name.
Number your carbon atoms so that your side group approaches first; that end is considered the #1 carbon end.
In the fifth step, we have to name the side groups to include them in the chemical name of our compound.
