Baeyer tension

The ring stress in alicyclic compounds is called Baeyer stress , also Baeyer ring stress or Baeyer ring stress and the like . By definition, the tension energy in the six-membered ring is 0. The energy can be derived from the deviation from the ideal tetrahedral angle in cyclohexane . According to the Baeyer model, the following stability series would apply: 3, 4, 5, 6. However, the Bayer model fails with cyclopropane due to the special binding properties, which cause an increase in stability. The actual stability series is therefore: 4, 3, 5, 6.

The Baeyer voltage is named after the Nobel Prize winner Adolf von Baeyer .
