WebMay 12, 2014 · Viewed 20k times. 46. 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 ∘ instead of the required 109.5 ∘. No book I have read mentions this reaction. 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. graphic card outputsWebAs 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. graphic card out of stock
