• Unsaturated Hydrocarbons - Hydrocarbons have a double bond between them. For example - ethylene $({\mathrm{CH}}_2={\mathrm{CH}}_2)$
• Saturated Hydrocarbons - Hydrocarbons have a single bond between them. For example - methane $\left({\mathrm{CH}}_4\right)$

Uses of Hydrocarbons -

• They are the main constituents of petroleum and natural gas.
