  2. Aliphatic compound - Wikipedia

    en.wikipedia.org/wiki/Aliphatic_compound

    Most aliphatic compounds are flammable, allowing the use of hydrocarbons as fuel, such as methane in natural gas for stoves or heating; butane in torches and lighters; various aliphatic (as well as aromatic) hydrocarbons in liquid transportation fuels like petrol/gasoline, diesel, and jet fuel; and other uses such as ethyne (acetylene) in welding.

  3. Aromatic compound - Wikipedia

    en.wikipedia.org/wiki/Aromatic_compound

    Examples of non-benzene compounds with aromatic properties are furan, a heterocyclic compound with a five-membered ring that includes a single oxygen atom, and pyridine, a heterocyclic compound with a six-membered ring containing one nitrogen atom. Hydrocarbons without an aromatic ring are called aliphatic. Approximately half of compounds known ...

  4. Hydrocarbon - Wikipedia

    en.wikipedia.org/wiki/Hydrocarbon

    Aromatic hydrocarbons, also known as arenes, which are hydrocarbons that have at least one aromatic ring. 10% of total nonmethane organic carbon emission are aromatic hydrocarbons from the exhaust of gasoline-powered vehicles. [4] The term 'aliphatic' refers to non-aromatic hydrocarbons.

  5. Aromaticity - Wikipedia

    en.wikipedia.org/wiki/Aromaticity

    The molecule heme contains an aromatic system with 22 π electrons. Chlorophyll also has a similar aromatic system. Aromatic compounds are important in industry. Key aromatic hydrocarbons of commercial interest are benzene, toluene, ortho-xylene and para-xylene. About 35 million tonnes are produced worldwide every year.

  6. Category:Aromatic compounds - Wikipedia

    en.wikipedia.org/wiki/Category:Aromatic_compounds

    Aromatic compounds, also known as arenes or aromatics, are chemical compounds that contain conjugated planar ring systems with delocalized pi electron clouds instead of discrete alternating single and double bonds. Typical aromatic compounds are benzene and toluene. They should satisfy Hückel's rule.

  7. Aromatization - Wikipedia

    en.wikipedia.org/wiki/Aromatization

    The process, which is catalyzed by platinum supported by aluminium oxide, is exemplified in the conversion methylcyclohexane (a naphthene) into toluene (an aromatic). [2] Dehydrocyclization converts paraffins (acyclic hydrocarbons) into aromatics. [3] A related aromatization process includes dehydroisomerization of methylcyclopentane to benzene:

  8. Alicyclic compound - Wikipedia

    en.wikipedia.org/wiki/Alicyclic_compound

    In organic chemistry, an alicyclic compound contains one or more all-carbon rings which may be either saturated or unsaturated, but do not have aromatic character. [1] Alicyclic compounds may have one or more aliphatic side chains attached.

  9. Hydrocarbon mixtures - Wikipedia

    en.wikipedia.org/wiki/Hydrocarbon_mixtures

    A hydrocarbon is any chemical compound that consists only of the elements carbon (C) and hydrogen (H). They all contain a carbon frame, and have hydrogen atoms attached to the frame. Often the term is used as a shortened form of the term aliphatic hydrocarbon. Most hydrocarbons are combustible. [2]
