What are Hydrocarbons? Compare saturated and unsaturated hydrocarbons?

Open in App

Solution

Hydrocarbons are compounds that are made up of only carbon and hydrogen.

Saturated hydrocarbon Unsaturated hydrocarbon

Carbon atoms are joined only by single bonds. Some of the carbon atoms are joined by double or by triple bonds.

They are less reactive due to the strong single covalent bond They are more reactive due to the presence of electrons in the double or triple bond.

They do not undergo addition reactions They undergo addition reaction.
