Web18 May 2015 · The activation strain model is a powerful tool for understanding reactivity, or inertness, of molecular species. This is done by relating the relative energy of a molecular complex along the reaction energy profile to the structural rigidity of the reactants and the strength of their mutual interactions: ΔE(ζ) = ΔE strain (ζ) + ΔE int (ζ).

WebStrain energy is the increase in energy due to imperfect overlap compared to the energy of an analogous system which has optimal overlap and the most bonding energy possible. This is shown for small rings in Figure 6.8. The methylene groups of cyclopropane are less stable by 9.1 kcal/mol than the methylene groups in open-chain hydrocarbons, and ... WebSteric Strain. The lowest energy form of a molecule is usually favored because it is the most natural structure, meaning there is little to no repulsion within groups and angle strain between bonds. But steric strain can occur when there are multiple bulky groups near each other in a molecule.
