The high-temperature phase I, stable between 186 K and the melting point 280 K, is a plastic crystal, which means the molecules retain some rotational degree of freedom. [9], Unlike benzene, cyclohexane is not found in natural resources such as coal. Another conformation of cyclohexane exists, known as boat conformation, but it interconverts to the slightly more stable chair formation. Cyclohexane has the lowest angle and torsional strain of all the cycloalkanes; as a result cyclohexane has been deemed a 0 in total ring strain. The molecule is related to cyclohexane ring by replacement of one hydrogen atom by a hydroxyl group. [5], Cyclohexyl is the alkyl substituent of cyclohexane and is abbreviated Cy. Cyclohexane is a petroleum product obtainedby distilling C4- 400°F boiling rangenaphthas, followed by fractionation andsuperfractionation; also formed by catalytichydrogenation of benzene. Did you know that some organic compounds can be referred to as cyclic and kind of resemble a loop of sorts? These cases involve rings of carbon atoms which are surprisingly awkward to draw tidily in a normal structural formula. Study the example discussed in this video.
