Now, coming to the stability of cyclopropyl methyl carbocation, it is symmetrically stabilized by both $\ce{C-C \sigma}$ (2-3 and 2-4) bonds. You may call it bent bond resonance with the vacant $\ce{p}$ orbital of the carbocation. WebAccording to the Bayer Theory, cyclopentane would be the most stable because its bond angle, 108°, is closest to the ideal angle of 109.5°. Cyclopropane would be the least stable one since it has the largest angle deviation of 49.5° (60° vs 109.5°). joytm limerick’s hospital-grade breast pump

WebSo again, this is the heat of combustion divided by the number of CH2 groups in kilojoules per mole. And this is a much better way to compare the stability of the cycloalkanes. Notice cyclopropane has the highest value here, 697. Cyclobutane goes down to 680, cyclopentane is 658 and cyclohexane is approximately 653. WebCyclopropane is necessarily planar (flat), with the carbon atoms at the corners of an equilateral triangle. The 60º bond angles are much smaller than the optimum 109.5º angles of a normal tetrahedral carbon atom, and the resulting angle strain dramatically influences the chemical behavior of this cycloalkane.
