The carbon atoms of the chair made up of cyclohexane roughly lie in one plane, and an axis can be drawn perpendicular to this plane. Each carbon atom of cyclohexane is bonded to two hydrogens. The bond to one of these hydrogen lies in the rough plane of the ring; this hydrogen is called Equatorial Hydrogen.

WebCyclohexane is rapidly rotating between the two most stable conformations known as the chair conformations in what is called the “Chair Flip” shown below. Several other notable cyclohexane conformations occur during the transition from one chair conformer to the other – the boat, the twist, and the half-chair. Why is cyclohexane not aromatic?
