WebNov 20, 2015 · Can you imagine that cyclopropane would have a lot of spatial crowding from the orbitals? Fortunately, the orbitals bend a little to compensate, but that isn't enough to completely stabilize it. This makes it reactive because it really wants to break those bonds and unbend the orbitals. WebIn contrast, cyclopentane & cyclohexane have least strain so they are found more readily and are very stable as compared to cyclopropane. Baeyer strain theory satisfactorily explains the typical reactivity and stability of smaller rings (from C3 to C5) i.e. Stability order follows : Cyclopropane < Cyclobutane < Cyclopentane
