WebTHE HALOGENATION OF ALKENES. This page looks at the reaction of the carbon-carbon double bond in alkenes such as ethene with halogens such as chlorine, bromine and iodine. This is called halogenation. Reactions where the chlorine or bromine are in solution (for example, "bromine water") are slightly more complicated and are treated separately ... WebThe bromine loses its original red-brown colour to give a colourless liquid. In the case of the reaction with ethene, 1,2-dibromoethane is formed,also know as ethylene dibromide. This decolourisation of bromine is often used as a test for a carbon-carbon double bond. Hence option B is a correct answer. Solve any question of Hydrocarbons with:-.
