WebFigure 4.4b 1,3-diaxial interaction. For mono-substituted cyclohexane, the equatorial-conformer is more stable than the axial-conformer because of the 1,3-diaxal interaction. Since the 1,3-diaxal interaction is essentially the steric strain, the larger the size of the substituent, the greater the interaction is. WebCyclohexane is a good example of a carbocyclic system that virtually eliminates eclipsing and angle strain by adopting non-planar conformations. Cycloheptane and cyclooctane have greater strain than cyclohexane, in large part due to transannular crowding (steric hindrance by groups on opposite sides of the ring).
