• alkane
  • The six-membered ring of the alkane, cyclohexane, has the 'chair' as its preferred conformation and through proton NMR it would be expected that the produced spectrum would show the different sorts of protons (axial and equatorial) resonating at different frequencies, and so two signals would be seen, due to the protons being in slightly different chemical environments.

  • methyl group
  • CHM with a methylethyl (or isopropyl) substituent group at the same position as the methyl group in 4-methylcyclohexanemethanol (cis-4-(1-methylethyl) cyclohexane methanol, CAS 13828-37-0) is regarded as a flavoring and fragrance agent, sometimes listed under the synonym p-menthan-7-ol, and was the subject of a review article on its toxicological and dermatological properties in 2008. (wikipedia.org)
  • Methylcyclohexane is a monosubstituted cyclohexane because it has one branching via the attachment of one methyl group on one carbon of the cyclohexane ring. (wikipedia.org)
  • atoms
  • In the case of the catalytic hydrogenation the aromatic part of the diisononyl phthalate is transformed to a cyclohexane ring by a formal addition of 6 hydrogen atoms while the alkyl and ester groups are not affected by the hydrogenation. (wikipedia.org)
  • slowly
  • When bicyclohexyl is heated to around 700K it slowly decomposes to cyclohexane and cyclohexene, as the pivot bond joining the two rings is the longest and weakest one. (wikipedia.org)
  • chemical
  • Cyclohexane conformations have been extensively studied in organic chemistry because they are the classical example of conformational isomerism and have noticeable influence on the physical and chemical properties of cyclohexane. (wikipedia.org)
  • This page provides supplementary chemical data on cyclohexane. (wikipedia.org)
  • Cyclohexane-1,2-diol is a chemical compound found in castoreum. (wikipedia.org)
  • However, the chemical reactivity of cyclohexane, is inconsistent with two types of hydrogens in a stable form of the molecule (for example, there is only one monochlorocyclohexane, not two, as would be predicted if axial and equatorial hydrogens could be replaced independently), but this is due to the presence of rapid ring inversion as explained above.

  • chair
  • In 1890, Hermann Sachse, a 28-year-old assistant in Berlin, published instructions for folding a piece of paper to represent two forms of cyclohexane he called symmetrical and unsymmetrical (what we would now call chair and boat). (wikipedia.org)
