Alkanes are a type of hydrocarbon compound that consist of only carbon and hydrogen atoms bonded together in a straight chain or branched structure. They are commonly found in natural gas, petroleum, and other fossil fuels. Alkanes can also be synthesized in the laboratory through various chemical reactions.
Alkanes are abundant in nature and can be found in various forms and concentrations in different environments. They are present in crude oil, natural gas, coal, and other fossil fuel deposits. Alkanes are also produced by living organisms as a byproduct of metabolism, and can be found in plant waxes, animal fats, and other biological materials.
Overall, alkanes are widely distributed in the environment and play important roles in various industrial processes, energy production, and biological functions. Their occurrence is therefore quite common and widespread.

Natural Sources:
- Petroleum and natural gas: Alkanes are the primary components of fossil fuels.
- Coal: Contains small amounts of alkanes.
- Plant and animal waxes: Consist of long-chain alkanes.
Industrial Sources:
- Fractional distillation of crude oil: Separates alkanes based on their boiling points.
- Cracking of larger hydrocarbons: Breaks down heavier hydrocarbons into alkanes.
- Fischer-Tropsch synthesis: Converts carbon monoxide and hydrogen into alkanes.
Occurrence by Chain Length:
- Methane (CH₄): Most abundant alkane, present in natural gas, wetlands, and landfills.
- Ethane (C₂H₆): Second most abundant, found in natural gas and crude oil.
- Propane (C₃H₈): Used as a fuel and refrigerant, found in natural gas and crude oil.
- Butane (C₄H₁₀): Used as a fuel and lighter gas, found in natural gas and crude oil.
- Pentane (C₅H₁₂): Liquid at room temperature, used as a solvent.
- Hexane (C₆H₁₄): Solvent used in paints and adhesives.
- Heptane (C₇H₁₆): Used as a cleaning solvent.
- Octane (C₈H₁₈): Key component in gasoline, determines its octane rating.
- Nonane (C₉H₂₀): Liquid used as a solvent and fuel.
- Decane (C₁₀H₂₂): Solid at room temperature, used as a heat transfer fluid.
Other Occurrences:
- Athabasca oil sands: Contains alkanes mixed with sand and minerals.
- Shale gas: Natural gas trapped in shale rock formations, rich in methane.
- Biogas: Produced by the anaerobic decomposition of organic matter, contains methane as the primary alkane.
