उत्तर
The compounds entirely consisting of carbons and hydrogens are known as Hydrocarbons. There are different categories in which hydrocarbons are divided out of which the two are:
(i) Saturated Hydrocarbons: The compounds of carbon having only single bonds between the carbon atoms are called saturated compounds. This includes alkanes, having a general formula CnH2n+2.
(ii) Unsaturated Hydrocarbons: The compounds of carbon having double and triple bonds between the carbon atoms are called unsaturated compounds. This includes alkenes and alkynes having general formula CnH2n and CnH2n-2, respectively.
Example
(i) Saturated hydrocarbon: C2H6 (Ethane)
Structure:
