Coulson and Moffitt proposed the carbon-carbon bonds in cyclopropane rings are bent based on quantum mechanical calculations. This idea of bent bonds is supported by electron density maps from X-ray reports. Molecular orbital principle clarifies that the overlap of orbital axes is maximized in cyclohexane, causing more powerful carbon-carbon bonds, whereas in cyclopropane the orbital overlap is considerably less, generating the bonds weaker and allowing for for ring-opening.
