The lowest energy conformation is the chair conformation; thus, it is the most popular. twist-boat and boat conformations are higher in energy than chair and are similar in energy levels, although. Chair-chair interconversion like other conformations we have studied, chair conformations are in a state of constant flux. because all the c-c bonds are interconnected, they cannot rotate independently but have to move together. for example, one end of the chair could "flip up" to put the cyclohexane ring in a boat conformation.. Drawing boat and chair conformations requires identifying the c-c bonds and the bonded substituents. the chair view is the more stable cyclohexane and the boat view is less stable, but both require 3-d representations of bent bonding patterns..
By twisting the boat conformation, the steric hindrance can be partially relieved, but the twist-boat conformer still retains some of the strains that characterize the boat conformer. finally, by lifting one carbon above the ring plane and the other below the plane, a relatively strain-free chair conformer is formed. this is the predominant. In the half-chair conformation 4 carbon atoms are located on a plane in which two bonds are fully eclipsed. twist or twist-boat (3. the boat and envelope forms are transition states between the twist forms and the twist and chair forms respectively..
