  2. Hydrocarbon - Wikipedia

    en.wikipedia.org/wiki/Hydrocarbon

    In the fossil fuel industries, hydrocarbon refers to naturally occurring petroleum, natural gas and coal, or their hydrocarbon derivatives and purified forms. Combustion of hydrocarbons is the main source of the world's energy. Petroleum is the dominant raw-material source for organic commodity chemicals such as solvents and polymers.

  3. Hydrocarbon economy - Wikipedia

    en.wikipedia.org/wiki/Hydrocarbon_economy

    Hydrocarbon economy is a term referencing the global hydrocarbon industry and its relationship to world markets. Energy used mostly comes from three hydrocarbons: petroleum, coal, and natural gas. Hydrocarbon economy is often used when talking about possible alternatives like the hydrogen economy. [1] [2]

  4. Saturated and unsaturated compounds - Wikipedia

    en.wikipedia.org/wiki/Saturated_and_unsaturated...

    The term is used in many contexts and for many classes of chemical compounds. Overall, saturated compounds are less reactive than unsaturated compounds. Saturation is derived from the Latin word saturare, meaning 'to fill'. [1]

  5. Functional group - Wikipedia

    en.wikipedia.org/wiki/Functional_group

    Hydrocarbons are a class of molecule that is defined by functional groups called hydrocarbyls that contain only carbon and hydrogen, but vary in the number and order of double bonds. Each one differs in type (and scope) of reactivity.

  6. Carbon-neutral fuel - Wikipedia

    en.wikipedia.org/wiki/Carbon-neutral_fuel

    Larger hydrocarbons [17] and ethanol [18] can also be produced from carbon dioxide and hydrogen. All synthetic hydrocarbons are generally produced at temperatures of 200–300 °C, and at pressures of 20 to 50 bar. Catalysts are usually used to improve the efficiency of the reaction and create the desired type of hydrocarbon fuel. Such ...

  7. Aliphatic compound - Wikipedia

    en.wikipedia.org/wiki/Aliphatic_compound

    Aliphatic compounds can be saturated, joined by single bonds (), or unsaturated, with double bonds or triple bonds ().If other elements (heteroatoms) are bound to the carbon chain, the most common being oxygen, nitrogen, sulfur, and chlorine, it is no longer a hydrocarbon, and therefore no longer an aliphatic compound.
