Cyclohexane process

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 … WebCyclohexane definition, a colorless, pungent, flammable liquid, C6H12, composed of a ring of six methylene groups, derived from crude petroleum by distillation or from benzene by …
