Reaction of eugenol with bromine

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. This decolourisation of bromine is often used as a test for a carbon-carbon double bond. If an aqueous solution of bromine is used ("bromine water"), you get a mixture of products. WebBromine, Br 2, reacts with fluorine, F 2, in gas phase, forming BrF. The product is difficult to obtain pure as BrF react with itself, forming Br 2, BrF 3 and BrF 5. Using excess fluorine at …
