  2. Structural formula - Wikipedia

    en.wikipedia.org/wiki/Structural_formula

    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 possibly arranged in the real three-dimensional space.

  3. Octane - Wikipedia

    en.wikipedia.org/wiki/Octane

    Octane is a hydrocarbon and an alkane with the chemical formula C 8 H 18, and the condensed structural formula CH 3 (CH 2) 6 CH 3.Octane has many structural isomers that differ by the location of branching in the carbon chain.

  4. 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] It has a substantially higher octane rating (RON 93.7) than n-pentane (61.7), and therefore there is interest in conversion from the latter. [9]

  5. Chemical formula - Wikipedia

    en.wikipedia.org/wiki/Chemical_formula

    For simple molecules, a condensed (or semi-structural) formula is a type of chemical formula that may fully imply a correct structural formula. For example, ethanol may be represented by the condensed chemical formula CH 3 CH 2 OH, and dimethyl ether by the condensed formula CH 3 OCH 3.

  6. Skeletal formula - Wikipedia

    en.wikipedia.org/wiki/Skeletal_formula

    The skeletal formula of the antidepressant drug escitalopram, featuring skeletal representations of heteroatoms, a triple bond, phenyl groups and stereochemistry. The skeletal formula, line-angle formula, bond-line formula or shorthand formula of an organic compound is a type of molecular structural formula that serves as a shorthand representation of a molecule's bonding and some details of ...

  7. 1-Butene - Wikipedia

    en.wikipedia.org/wiki/1-Butene

    1-Butene (IUPAC name: But-1-ene, also known as 1-butylene) is the organic compound with the formula CH 3 CH 2 CH=CH 2. It is a colorless gas. But-1-ene is an alkene easily condensed to give a colorless liquid. It is classified as a linear alpha-olefin (terminal alkene). [2] It is one of the isomers of butene (butylene). It is a precursor to ...

  8. 2-Methylpentane - Wikipedia

    en.wikipedia.org/wiki/2-Methylpentane

    2-Methylpentane, trivially known as isohexane, is a branched-chain alkane with the molecular formula C 6 H 14.It is a structural isomer of hexane composed of a methyl group bonded to the second carbon atom in a pentane chain.

  9. Neopentane - Wikipedia

    en.wikipedia.org/wiki/Neopentane

    Neopentane, also called 2,2-dimethylpropane, is a double-branched-chain alkane with five carbon atoms. Neopentane is a flammable gas at room temperature and pressure which can condense into a highly volatile liquid on a cold day, in an ice bath, or when compressed to a higher pressure.
