Different conformers of cyclohexane contain different energies. Place the conformations of cyclohexane in their appropriate positions in the energy diagram below.
Homework Answers
Conformations are formed due to free rotation around carbon-carbon single bond. The kinetic energy present in the molecule because of various collisions is enough to rotate carbon-carbon single bond. The graph showing the energy of various conformation of cyclohexane is given and the conformation that suits the mentioned energy level needs to be placed.
Compare the stability of various conformation of cyclohexane and then place them on the graph at suitable positions.
Various conformations of cyclohexane are formed by the rotation of C-C single bond as shown below:
• Chair conformation: It the most stable conformation of cyclohexane molecule, that is free from any strain.
• Boat conformation: It is formed by the twisting of chair conformation. It contains angle strain as well as torsional strain.
• Twist boat: Due to flexibility of boat conformation it can be twisted and result in the formation of twist boat conformation. Torsional strain is minimized in this conformation.
• Half chair: It is the least stable conformation of cyclohexane molecule.
Arrange the conformations of cyclohexane in the increasing stability order based on angle strain and torsional strain in the conformation comparative to each other as shown below:

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.
