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. WebThe reaction of alkenes with bromine water: C 2 H 4 + Br 2 ———-> C 2 H 4 Br 2 ethene + bromine———> 1, 2-dibromoethane The bromine has added across the double bond. Bromine water does not react with saturated compounds (alkanes) because they do not have a double bond to ‘open up’. Hydrogen reacts with alkenes to form alkanes: playera harley quinn

WebNov 1, 2010 · As but-2-ene bubbles through the bromine solution and reacts with the bromine, the bromine adds across the double bond and so the solution changes from brown to colourless. This is why the decolouration of a bromine solution is used as an analytical test for alkenes. WebAs the bromine molecule approaches the ethene, the electrons in the pi bond tend to repel the electrons in the bromine-bromine bond, leaving the nearer bromine slightly positive and the further one slightly negative.
