Hydrocarbons are organic chemical compounds composed entirely of hydrogen and carbon atoms. They are the building blocks for a vast array of organic molecules and are found in many natural resources, most notably petroleum and natural gas. The simplest hydrocarbon is methane, with the chemical formula CH4.

The structure of hydrocarbons is based on chains or rings of carbon atoms, with hydrogen atoms attached to these carbon atoms. The ratio of carbon to hydrogen atoms varies, leading to different types of hydrocarbons. Alkanes are saturated hydrocarbons, meaning they contain only single bonds between carbon atoms. Their general formula is CnH2n+2. Examples include ethane (C2H6) and propane (C3H8).

Alkenes are unsaturated hydrocarbons that contain at least one carbon-carbon double bond. They have the general formula CnH2n. Ethene (C2H4) is the simplest alkene. Alkynes are also unsaturated hydrocarbons, characterized by the presence of at least one carbon-carbon triple bond. Their general formula is CnH2n-2. Ethyne (acetylene, C2H2) is the simplest alkyne. Cyclic hydrocarbons, such as cyclopropane and benzene, feature carbon atoms arranged in a ring structure.

Hydrocarbons are fundamental to modern society, serving as primary sources of energy, such as gasoline and natural gas. They are also crucial raw materials in the petrochemical industry, used to manufacture plastics, synthetic fibers, solvents, and numerous other products. Their diverse structures and properties allow for a wide range of applications.
