Nomenclature describes the whole structure of organic molecules using different naming programs, such as trivial, radicofunctional, and IUPAC substitutive nomenclature.
Coulson and Moffitt proposed which the carbon-carbon bonds in cyclopropane rings are bent depending on quantum mechanical calculations. This idea of bent bonds is supported by electron density maps from X-ray studies. Molecular orbital principle explains that the overlap of orbital axes is maximized in cyclohexane, leading to more robust carbon-carbon bonds, While in cyclopropane the orbital overlap is much less, generating the bonds weaker and allowing for for ring-opening.
