  2. Lewis structure - Wikipedia

    en.wikipedia.org/wiki/Lewis_structure

    Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.

  3. Butane - Wikipedia

    en.wikipedia.org/wiki/Butane

    Butane (/ ˈ b juː t eɪ n /) is an alkane with the formula C 4 H 10. Butane exists as two isomers, n-butane with connectivity CH 3 CH 2 CH 2 CH 3 and iso-butane with the formula (CH 3) 3 CH. Both isomers are highly flammable, colorless, easily liquefied gases that quickly vaporize at room temperature and pressure.

  4. 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.

  5. Newman projection - Wikipedia

    en.wikipedia.org/wiki/Newman_projection

    Butane molecule represented on a staggered and eclipsed Newman projection down a carbon-carbon bond Butane molecule and all of its possible Newman conformations represented on a relative energy diagram. The diagram takes staggered and eclipsed conformations, as well as gauche and anti interactions into account.

  6. 2,2-Dimethylbutane - Wikipedia

    en.wikipedia.org/wiki/2,2-Dimethylbutane

    In laboratory settings, it is commonly used as a probe molecule in techniques which study the active sites of metal catalysts. Such catalysts are used in hydrogen-deuterium exchange, hydrogenolysis, and isomerization reactions. It is well suited to this purpose as 2,2-dimethylbutane contains both an isobutyl and an ethyl group. [12]

    The molecular formula C 4 H 10 (molar mass: 58.12 g/mol, exact mass: 58.0783 u) may refer to: Butane , or n -butane Isobutane , also known as methylpropane or 2-methylpropane

  9. Lewis acids and bases - Wikipedia

    en.wikipedia.org/wiki/Lewis_acids_and_bases

    A Lewis base is an atomic or molecular species where the highest occupied molecular orbital (HOMO) is highly localized. Typical Lewis bases are conventional amines such as ammonia and alkyl amines. Other common Lewis bases include pyridine and its derivatives. Some of the main classes of Lewis bases are
