  1. Cyclopropane A ball-and-stick model of cyclopropane shows the ring strain when the bond angles are deformed from their normal 109.5° to 60°.

  2. Cyclobutane A ball-and-stick model of cyclobutane shows the ring strain when the bond angles are deformed from their normal 109.5° to approximately 90°.

  3. Cyclopentane The ball-and-stick model of cyclopentane reveals a nearly planar molecule with bond angles of 108°.

  4. Cyclohexane: Chair and Boat Conformations The chair conformation of cyclohexane can be twisted into the boat conformation.

  5. Cyclohexane: Chair and Boat Conformations The chair conformation of cyclohexane can be twisted into the boat conformation. Further twisting results in a second chair conformation. By labeling one axial substituent with a white sphere you can see how the axial position of one chair becomes equatorial by twisting into the second chair conformation.
