  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. 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 ...

    Detection of structures, text, and arrows, and their automatic placement; Can automatically draw rings and other structures - has all standard amino acids and nucleic acids in a built-in library; Retrieval of structures from a network database based on CAS number, formula, or name; Retrieval of information on a molecule based on a drawing

  5. Lewis structure - Wikipedia

    en.wikipedia.org/wiki/Lewis_structure

    Another shorthand structural diagram is the skeletal formula (also known as a bond-line formula or carbon skeleton diagram). In a skeletal formula, carbon atoms are not signified by the symbol C but by the vertices of the lines. Hydrogen atoms bonded to carbon are not shown—they can be inferred by counting the number of bonds to a particular ...

  6. 3,3-Dimethylpentane - Wikipedia

    en.wikipedia.org/wiki/3,3-Dimethylpentane

    In 1929 Graham Edgar and George Calingaert made 3,3-dimethylpentane and measured its physical characteristics for the first time. The measurements were at 20 °C, not the standard conditions used in later times.

  7. 2,2-Dimethylpentane - Wikipedia

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

    The type of clathrate formed is called "clathrate H". 2,2-Dimethylpentane was the first compound for which the structure was determined. The clathrate has 34 molecules of water per molecule, and also has xenon and hydrogen sulfide as helper molecules. The crystals are hexagonal in form and melt at 0.6 °C.

  8. Triptane - Wikipedia

    en.wikipedia.org/wiki/Triptane

    Triptane, or 2,2,3-trimethylbutane, is an organic chemical compound with the molecular formula C 7 H 16 or (H 3 C-) 3 C-C(-CH 3) 2 H. It is therefore an alkane, specifically the most compact and heavily branched of the heptane isomers, the only one with a butane (C 4) backbone.

  9. 2-Methylheptane - Wikipedia

    en.wikipedia.org/wiki/2-Methylheptane

    2-Methylheptane is a branched-chain alkane and an isomer of octane.It is an heptane molecule with a methyl group attached to its second atom. It is a flammable colorless liquid used as fuel.
