The chair conformation is considered to be the lowest energy conformation because it lacks this means that the chair conformation is the structure that is observable in most reactions of cyclohexane. B The higher energy chair conformation contains one axial methyl group and one equatorial methyl group. For example the energy difference of the axial and equatorial isopropyl cyclohexane is 92 kJmol. I know that sounds kind of juvenile but once again there are so many people that struggle to draw this weird shape that its not even worth it not to go over it. We should just go over.
