Cyclohexane stability vs benzene

WebJan 23, 2024 · If you miss it out, you are drawing cyclohexane and not benzene. Relating Electronic Structrure to Properties of Benzene The shape of benzene: Benzene is a planar regular hexagon, with bond angles of 120°. This is easily explained. It is a regular hexagon because all the bonds are identical. WebIn practice, 1,3-cyclohexadiene is slightly more stable than expected, by about 2 kcal, presumably due to conjugation of the double bonds. Benzene, however, is an extraordinary 36 kcal/mole more stable than expected. This sort of stability enhancement is now accepted as a characteristic of all aromatic compounds.
