  2. Cyclohexane - Wikipedia

    en.wikipedia.org/wiki/Cyclohexane

    The 6-vertex edge ring does not conform to the shape of a perfect hexagon. The conformation of a flat 2D planar hexagon has considerable strain because the C-H bonds would be eclipsed . Therefore, to reduce torsional strain , cyclohexane adopts a three-dimensional structure known as the chair conformation , which rapidly interconvert at room ...

  3. Cyclohexane conformation - Wikipedia

    en.wikipedia.org/wiki/Cyclohexane_conformation

    Cyclohexane is the most stable of the cycloalkanes, due to the stability of adapting to its chair conformer. [4] This conformer stability allows cyclohexane to be used as a standard in lab analyses. More specifically, cyclohexane is used as a standard for pharmaceutical reference in solvent analysis of pharmaceutical compounds and raw materials.

  4. Cyclohexane-1,2,3,4,5,6-hexol - Wikipedia

    en.wikipedia.org/wiki/Cyclohexane-1,2,3,4,5,6-hexol

    Cyclohexane-1,2,3,4,5,6-hexol is a family of chemical compounds with formula C 6 H 12 O 6, whose molecule consists of a ring of six carbon atoms, each bound to one hydrogen atom and one hydroxyl group (–OH). There are nine stereoisomers, that differ by the position of the hydroxyl groups relative to the mean plane of the ring.

  5. Allylic strain - Wikipedia

    en.wikipedia.org/wiki/Allylic_strain

    Allylic strain in an olefin. Allylic strain (also known as A 1,3 strain, 1,3-allylic strain, or A-strain) in organic chemistry is a type of strain energy resulting from the interaction between a substituent on one end of an olefin (a synonym for an alkene) with an allylic substituent on the other end. [1]

  6. Ring flip - Wikipedia

    en.wikipedia.org/wiki/Ring_flip

    Cyclohexane is a prototype for low-energy degenerate ring flipping. Two 1 H NMR signals should be observed in principle, corresponding to axial and equatorial protons. However, due to the cyclohexane chair flip, only one signal is seen for a solution of cyclohexane at room temperature, as the axial and equatorial proton rapidly interconvert ...

    WASHINGTON (Reuters) -U.S. President Donald Trump said on Sunday, without citing evidence, that "certain classes of people" in South Africa were being treated "very badly" and that he would cut ...

  8. Cyclohexanehexone - Wikipedia

    en.wikipedia.org/wiki/Cyclohexanehexone

    Cyclohexanehexone, also known as hexaketocyclohexane and triquinoyl, is an organic compound with formula C 6 O 6, the sixfold ketone of cyclohexane.It is an oxide of carbon (an oxocarbon), a hexamer of carbon monoxide.
