hydrocarbon
Structures assumed by hydrogen (H) and carbon (C) molecules in four common hydrocarbon compounds.
Hydrocarbons are organic chemical compounds composed exclusively of carbon and hydrogen atoms. Because of their chemical structure, they serve as the principal constituents of fossil fuels, which are the primary sources of energy used in modern life.123
Fuels that contain hydrocarbons include:
- Petroleum: Crude oil is primarily composed of hydrocarbons, including paraffins, naphthenes, and aromatics. Refined products derived from petroleum, such as gasoline, are also hydrocarbon-based.45
- Natural gas: This is a major source of hydrocarbons, often consisting of simple alkanes like methane.14
- Bitumens, tar sands, and heavy oils: These complex, viscous substances are rich in hydrocarbon content, often containing heavier compounds like asphaltenes.463
- Coal: As a fossil fuel formed from organic matter, coal contains significant carbon-based compounds, including hydrocarbons.3
These fuels are essential for energy production, powering vehicles, and generating electricity.23
