WebAug 19, 2024 · Cyclohexane is a good example of a carbocyclic system that virtually eliminates eclipsing and angle strain by adopting non-planar conformations. Cycloheptane and cyclooctane have greater strain than cyclohexane, in large part due to transannular crowding (steric hindrance by groups on opposite sides of the ring). WebFor cyclopentane, this bond angle is 108 degrees, and 108 degrees is pretty close to 109.5 degrees, closer than it would be for cyclohexane; This bond angle is 120 degrees. And so the theory was, cyclopentane is the most stable out of the cycloalkanes, because this bond angle is closest to 109.5 degrees.
