TOPIC – 03 : Nomenclature of a few important Aliphatic Compounds

IUPAC Nomenclature of a few important Aliphatic Compounds  

 

The IUPAC nomenclature of alkanes, alkenes and alkynes are discussed in the subsection below :


 

 

1.      Alkanes : The general formula of alkanes corresponds to CnH2n+2. The Suffix ‘ane’ is generally used to describe alkanes.  

                   Examples for the nomenclature of alkanes as per IUPAC guidelines include methane for the compound CH4 and butane for the compound C4H10

 

2.    Alkenes : The general formula of alkynes corresponds to CnH2n.                  

The suffix ‘ene’ is used to describe via IUPAC norms.  

                   Examples for the nomenclature of alkenes include the name ethene used to describe the compound given by C2H4 and propene used to describe the compound given by C3H6

 

3.    Alkynes : The general formula of alkynes corresponds to CnH2n-2.   The suffix “yne’ is generally used to describe alkynes.

                           An example of the IUPAC nomenclature of alkynes is ethyne used to describe the compound given by C2H2.
