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?
General formula of saturated hydrocarbons (alkanes): CnH2n+2
Example: Ethane – C2H6
General formula for unsaturated hydrocarbons:
Example: Ethene – C2H4
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.
