WebWhen bromine is added to cyclopropane, for instance, tribromopropane is formed. If light is present, this can still happen - but a substitution reaction will also occur. It is very difficult to burn cyclopropane because the ring gets strained, resulting in rupture. 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°). open spx on windows
