Ethene reacting with bromine water
WebBromine water is an oxidizing, intense brown mixture containing diatomic bromine (Br 2) dissolved in water (H 2 O). It is often used as a reactive in chemical assays of recognition for substances which react with … 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’.

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. south willingham lincsWebThe old name for the alkanes was the paraffins. ? Alkynes may have one or more triple bonds in their structure. ? Alkanes are much more stable than alkenes because of the presence of the C=C double bond. ? The simplest aromatic compound is benzene.
