Web8 years ago Why does cyclopropane react with bromine? In my exam, I was asked why cyclopropane could decolourise bromine water (indicating that it reacted with the bromine ). All I could guess was that it is related to the high angle strain in cyclopropane, as the C–C–C bond angle is $60^\circ$ instead of the required $109.5^\circ$. WebJul 7, 2024 · What happens when cyclohexane reacts with bromine? Cyclohexane has no pi-unsaturation and is therefore not nucleophilic. It does not react with bromine unless energy in the form of light or heat is applied. In such a case a free-radical substitution reaction occurs. Cyclohexene is a typical alkene, and benzene and anisole are aromatic … WebJun 7, 2024 · Why does cyclopropane react with bromine? organic-chemistry halides 18,251 Solution 1 The following ring opening reaction will occour: You are quite right about the angle strain.
