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. WebCycloalkanes generally have less ring strain than cycloalkenes, which is seen when comparing cyclopropane and cyclopropene. Angle strain in alkenes. Cyclic alkenes are subject to strain resulting from distortion of the sp 2-hybridized carbon centers.Illustrative is C 60 where the carbon centres are pyramidalized. This distortion enhances the reactivity …
