WebHowever, molecules, such as cyclohexane and cyclopentane, would have a much lower ring strain because the bond angle between the carbons is much closer to 109.5 o. Below are some examples of cycloalkanes. Ring strain can be seen more prevalently in the cyclopropane and cyclobutane models. WebMar 15, 2024 · Actually, cyclohexane and other larger rings are not flat, but are puckered so that each bond angle can be 109 0 28’. Consequently the ring becomes strainless and stable. For example, the cyclohexane can exist in two non-planar strainless puckered (folded) forms. Factors affecting the stability of conformations 1.
