Problem #9. In addition to the chair conformations, cyclohexane derivatives also have half-chair, twist boat, and boat conformations. These are all higher energy than chair conformations. In fact, the half- chair is the transition state between the chair and the twist boat, and the boat is the transition state between two different twist boat conformations.
