There are two equivalent chair conformations. At any point on the chair that sticks down draw the axial hydrogen straight down. chair conformation axial hydrogens.
Chair Conformation Axial Hydrogens, Remember that in the chair form of cyclohexane which has already been established as the most stable conformation by several kcalmol there are hydrogens in two distinct positions. In this process the equa-torial hydrogens have become axial and the axial hydrogens have become equatorial. The bonds to one type are parallel to the axis of the ring.
