Reaction of ethene with bromine water
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: 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 ...

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. bio chamberWebJan 23, 2024 · The reaction with bromine happens at room temperature.
