Chair-to-chair interconversion for a substituted cyclohexane using the HGS model kit. The model should "snap" from one chair into the other chair because when it is not in a chair there is some strain energy in the plastic model just the same as in the actual molecules. If your kit does not easily go from one chair into the other then "wiggle" the bonds in an assembled chair a lot and quickly until then loosen up.
