Hydro Carbons

Hydro carbons are one of the simplest organic compounds because they are called they are composed of just two element only, which is carbon and hydrogen. All hydrocarbon have the molecular formula C_xH_y, where x and y represent positive whole numbers. Some examples are methane, CH₄, (x=1, y=4) hexane C₆H₁₄ (x=6, y=14). They are further divided into two main groups which are the aliphatic hydrocarbons and the aromatic hydrocarbons, depends on their structure.

Hydrocarbon can be gotten naturally from coal, natural gas and petroleum. These are often known as fossil fuels because they are; the remains of plant and animals that died millions if years ago and; used mainly as fuels, that is burnt to release heat or other forms of energy.
 Coal, petroleum and natural gas are solid, viscous liquid and gaseous fuels respectively.
