    en.wikipedia.org/wiki/Cyclopentane

    Cyclopentane is also used in the manufacture of synthetic resins and rubber adhesives. [citation needed] Cyclopentane is a minor component of automobile fuel, with its share in US gasoline varying between 0.2 and 1.6% in early 1990s [8] and 0.1 to 1.7% in 2011. [9] Its research and motor octane numbers are reported as 101 or 103 and 85 or 86 ...

    en.wikipedia.org/wiki/Pentane

    Pentane is an organic compound with the formula C 5 H 12 —that is, an alkane with five carbon atoms. The term may refer to any of three structural isomers, or to a mixture of them: in the IUPAC nomenclature, however, pentane means exclusively the n-pentane isomer, in which case pentanes refers to a mixture of them; the other two are called isopentane (methylbutane) and neopentane ...

    (1R,3R)-1,2,3-Trimethylcyclopentane is an organic hydrocarbon alicyclic cycloalkane compound with the molecular formula C 8 H 16. It is a saturated cyclopentane with three methyl substituents branching off carbons 1,2, and 3.

  6. Isopentane - Wikipedia

    en.wikipedia.org/wiki/Isopentane

    Isopentane is a major component (sometimes 30% or more) of natural gasoline, an analog of common petroleum-derived gasoline that is condensed from natural gas. [4] Its share in commercial car fuel is highly variable: 19–45% in 1990s Sweden, [ 13 ] 4–31% in 1990s US [ 14 ] and 3.6–11% in the US in 2011. [ 15 ]

    Skeletal structural formula of Vitamin B 12. Many organic molecules are too complicated to be specified by a molecular formula. The structural formula of a chemical compound is a graphic representation of the molecular structure (determined by structural chemistry methods), showing how the atoms are connected to one another.

  8. Cycloalkane - Wikipedia

    en.wikipedia.org/wiki/Cycloalkane

    Eclipsing of hydrogen atoms is an important destabilizing effect, as well. The strain energy of a cycloalkane is the increase in energy caused by the compound's geometry, and is calculated by comparing the experimental standard enthalpy change of combustion of the cycloalkane with the value calculated using average bond energies.

  9. Pentene - Wikipedia

    en.wikipedia.org/wiki/Pentene

    Pentenes are alkenes with the chemical formula C 5 H 10.Each molecule contains one double bond within its molecular structure. Six different compounds are in this class, differing from each other by whether the carbon atoms are attached linearly or in a branched structure and whether the double bond has a cis or trans form.
