In methylcyclohexane, for example, there are two conformational isomers, one with the methyl group axial and one with the methyl group equatorial. The two interconvert through ring flipping.

Is a ring flip a conformational change?

Cyclohexane undergoes a conformational change known as the ring-flip process in which each axial substituent becomes equatorial and each equatorial becomes axial. The substituents swap positions because the carbon skeleton undergoes inversion with respect to a plane slicing through the center of the ring.

Are ring flips enantiomers?

Another interesting feature of this molecule is that a ring flip produces the enantiomer. Since both enantiomers have the same steric biases and are equal in energy, the ring flips between the enantiomers rapidly at room temperature.
