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 angle strain because its bonds are not 109.5 degrees; the torsional strain would also be considerable because all of the bonds would be eclipsed bonds. Therefore, to reduce torsional strain, cyclohexane adopts a three-dimensional structure known as the chair conformation, which rapidly interconvert at room temperature via a process known as a chair … WebAlternatively, cyclohexanone can be produced by the partial hydrogenation of phenol : C 6 H 5 OH + 2 H 2 → (CH 2) 5 CO This process can also be adjusted to favor the formation of cyclohexanol. [11] ExxonMobil developed a process in which benzene is hydroalkylated to cyclohexylbenzene.
