Forskellige konformationer kan have forskellige egenskaber, herunder stabilitet og kemisk reaktivitet. Historisk baggrund [ redigér rediger kildetekst] In organic chemistry, cyclohexane conformations are any of several three-dimensional shapes adopted by molecules of cyclohexane. Because many compounds feature structurally similar six-membered rings, the structure and dynamics of cyclohexane are important prototypes of a wide range of compounds. The … See more Another way to compare the stability within two molecules of cyclohexane in the same conformation is to evaluate the number of coplanar carbons in each molecule. Coplanar carbons are carbons that are all on the same plane. … See more Chair to chair The interconversion of chair conformers is called ring flipping or chair-flipping. Carbon–hydrogen bonds that are axial in one configuration … See more Conformational equilibrium is the tendency to favor the conformation where cyclohexane is the most stable.
