Reaction of ethene with bromine
Web2. At school, we are taught that in bromine water, the following equilibrium is present: B r X 2 + H X 2 O ⇌ B r O H + H B r. Therefore, when you add an alkene to bromine water, you don't get bromination, but rather the B r O H reacts instead and you get the following reaction (lets say for ethene for example): C X 2 H X 4 + B r O H C X 2 H X ... WebThe reaction of ethene with Br 2 to form 1,2-dibromoethane is an addition reaction. The atoms that add to the double bond are located on adjacent carbon atoms, a common characteristic of addition reactions of alkenes. We can easily see the evidence for the addition of bromine to an alkene. Bromine is red-orange.
