Additional information :-

Full form of IUPAC :-

• International union of pure and applied chemistry.

The number of carbon atoms in a hydrocarbon is indicated by using the following stems :

• For 1 carbon it is indicated by Meth
• For 2 carbon it is indicated by Eth
• For 3 carbon it is indicated by prop
• For 4 carbon it is indicated by but
• For 5 carbon it is indicated by pent
• A saturated hydrocarbon containing single bonds is indicated by - ane.
• An unsaturated hydrocarbon containing double bonds is indicated by - ene.
• An unsaturated hydrocarbon containing triple bonds is indicated by - yne.

★ IUPAC Rules :

• At first you should identify the longest carbon chain. This chain is called as parent chain.

• Then, Identify all of the substituents as well as functional groups.

• Number the carbons of the parent chain from the end that gives us the substituents to the lowest numbers.

• It may occur that if there are two or more different substituents they should be listed in a proper alphabetical order using the base name.

• A hydrocarbon is designated by the prefix cyclo- which appears directly in front of the base name.

• Commas should be used between numbers and dashes should be used between letters and numbers.

• No space should be their in the name of the respective hydrocarbon.
