  3. Newman projection - Wikipedia

    en.wikipedia.org/wiki/Newman_projection

    This projection most commonly sights down a carbon-carbon bond, making it a very useful way to visualize the stereochemistry of alkanes. A Newman projection visualizes the conformation of a chemical bond from front to back, with the front atom represented by the intersection of three lines (a dot) and the back atom as a circle.

  4. Alkane - Wikipedia

    en.wikipedia.org/wiki/Alkane

    Alkanes have the general chemical formula C n H 2n+2. The alkanes range in complexity from the simplest case of methane (CH 4), where n = 1 (sometimes called the parent molecule), to arbitrarily large and complex molecules, like pentacontane (C 50 H 102) or 6-ethyl-2-methyl-5-(1-methylethyl) octane, an isomer of tetradecane (C 14 H 30).

    en.wikipedia.org/wiki/Molecular_model

    John Dalton represented compounds as aggregations of circular atoms, and although Johann Josef Loschmidt did not create physical models, his diagrams based on circles are two-dimensional analogues of later models. [2] August Wilhelm von Hofmann is credited with the first physical molecular model around 1860. [3]

  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. Using a quantitative structure-activity relationship (QSAR) prediction model, 2-Methylpentane has a research octane ...
