what are hydrocarbon?write the name and the general formula of (i) saturated hydrocarbons, (ii) unsaturated hydrocarbons, and draw the structure of one hydrocarbons of each type.how can an unsaturateds hydrocarbon be made saturated?

Compounds containing only hydrogen and carbon are called hydrocarbons.they may be classifies as saturated hydrocarbons and unsaturated hydrocarbons.
General formula of saturated hydrocarbons (alkanes): CnH2n+2
Example: Ethane – C2H6

General formula for unsaturated hydrocarbons:
Alkenes: CnH2n
Example: Ethene – C2H4

Alkynes: CnH2n-2
Example: Ethyne – C2H2

Unsaturated hydrocarbons can be mage saturated by hydrogenation reaction in which hydrogen atoms are added at the double or triple bond of the unsaturated hydrocarbon.
Example: hydrogenation of ethene to ethane.
