Cyclohexane cyclopentane
WebAccording to the Bayer Theory, cyclopentane would be the most stable because its bond angle, 108°, is closest to the ideal angle of 109.5°. Cyclopropane would be the least stable one since it has the largest angle deviation of 49.5° (60° vs 109.5°). WebFeb 14, 2024 · A planar cyclopentane would have bond angels 90 o and five pairs of eclipsing \(\ce{H's}\), but it is puckered that increases angle strain slightly but significantly reduces the eclipsing strain, resulting in an overall angle strain ~25 kJ/mol. If for \(\ce{C's}\) of cyclopentane are placed in one plane, the fifth is raised up giving it an ...

However, this strain, together with the eclipsing strain inherent in a planar structure, can be relieved by puckering the ring. Cyclohexane is a good example of a carbocyclic system that virtually eliminates eclipsing and angle strain by adopting non-planar conformations.
