Hydrocarbons are defined as the compounds which are composed of Hydrogen and Carbon atoms.
(i)The names and general formula for saturated Hydrocarbons is Alkane and the formula is: CnH2n+2. The 'n' represents number of carbon atoms in molecule of the alkane.
(ii) The names and general formula for unsaturated hydrocarbons are: Alkene and Alkyne. The general formula for alkene is: CnH2n and for Alkyne, it is : CnH2n-2
Structure of saturated hydrocarbon:
Molecular formula for 1 carbon atom = CH4
Structure of unsaturated hydrocarbon:
Molecular formula for 2 carbon atom is Ethene C2H4
The structure of Ethene is as follows:
Molecular formula for 2 carbon atom is Ethyne C2H2
H-C=C-H
Unsaturated hydrocarbon can be made a saturated hydrocarbon by addition reaction. On addition of Hydrogen in presence of Nickle as catalyst, to a unsaturated hydrocarbon, results in formation of a saturated hydrocarbon. The chemical reaction is as follows:
This reaction is called Hydrogenation.
