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 … WebJan 30, 2024 · It performs the function of a non-polar solvent.

WebCyclohexane oxidation is an important industrial process, but as the product is more easily oxidised than the substrate, the cyclohexane conversions need to be kept low (∼4%) such as to retain high selectivity for cyclohexanone and cyclohexanol (∼70–85%). This has prompted much research into the development of new and more selective ...
