Name: Saturated hydrocarbons.
Characteristic: Hydrocarbons in which the carbon atoms are connected by single bonds only.
Saturated hydrocarbons are also called Alkanes.
Name: Unsaturated hydrocarbons.
Characteristic: Hydrocarbons in which the carbon atoms are connected by double bonds or triple bonds are called unsaturated hydrocarbons.
Unsaturated hydrocarbons are of 2 types, Alkenes and Alkynes.
Name: Alkenes.
Characteristic: Unsaturated hydrocarbons in which the carbon atoms are connected by at least one double bond.
Name: Alkynes.
Characteristic: Unsaturated hydrocarbons in which the carbon atoms are connected by at least one triple bond are called alkynes.
