Hydrocarbons are compounds of hydrogen and carbon. They are found in petroleum and natural gases. Methane (CH4), Ethane (C2H6), propane (C3H8) and butane (C4H10) are some examples of hydrocarbons.

The first 4 are hydrocarbon gases, the next 13 are liquids, and the rest are solid.

Uses of Hydrocarbons

Hydrocarbons are used as fuel.

Natural gas mainly consists of methane. The residuals of plants and animals are used to make left gas, which is mainly methane gas.

Methane gas is also known as marsh gas, because it is formed by decomposition of fauna and flora in marshy areas.

Butane is brought into liquid state by pressure and (LPG) (liquid petroleum gas) is filled into the cylinder.
