Interconversion Around the Single Bond of Rings

3 Interconversion Around the Single Bonds of Rings Cyclohexane at room temperature exists as rapidly interconverting chair forms. 

The equatorial and axial methylene protons of methylcyclohexane are also rapidly interconverting pairs, but the two interconverting chair forms are dif- 

In a fused cyclohexane ring, such as those of steroids, the rings are frozen at room temperature and the axial and equatorial protons of each CH2 group are not chemical-shift equivalent.
