Chair Conformation Of Cyclohexane Axial And Equatorial. At each position one substituent is axial loosely perpendicular to the ring and one is equatorial loosely in the plane of the ring. At 100 c 91 3 of equatorial conformation and 8 7 of axial conformation exists in equilibrium.

Axial and equatorial are types of bonds found in the chair conformation of cyclohexane the chair conformation is the most stable conformation of cyclohexane axial positions are perpendicular to the plane of the ring and equatorial positions are around the plane of the ring the bond angles in this conformation are 110 9. A cyclohexane chair contains two kinds of hydrogens axial hydrogens and equatorial hydrogens. Axial substituents are labeled in red below.
This too is almost free of angle strain but in contrast has torsional strain associated with eclipsed bonds at the four of the c atoms that form the side of the boat.
Axial substituents are labeled in red below. Thus at 50 c 93 8 of equatorial conformation and 6 2 of axial conformation exists in equilibrium. A second much less stable conformer is the boat conformation. The chair conformation is the most stable conformation of cyclohexane.
