WebJul 14, 2024 · However, in cycloheptane (n = 7), there is torsional strain due to eclipsing interactions between H atoms, like in smaller rings, and also steric strain caused by transannular repulsive interactions, which are characteristic of medium-sized rings . Cycloheptane is therefore not strain-free and experiences pseudorotation [10,11,12]. WebThis bond angle causes cyclopropane and cyclobutane to have a high ring strain. However, 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.
