Ethene reacts with bromine water
Webbromine (water or solution) During the test for unsaturated hydrocarbons, what colour is present (if any) at the beginning of the test? orange/ brown If bromine water remains brown/orange when mixed with a hydrocarbon, it must mean the hydrocarbon is of what type? alkane Complete the following sentence. WebAlkene's double bond is attacked by the bromine atom, which causes single bonds to form in its stead. On the other hand, when the same procedure is carried out with alkanes, no such change is noticed, and the solution's color stays brown. For instance, when ethylene reacts with bromine water, the major result is 1,2 dibromoethane, which is ...

Other alkenes react in just the same way. Manganate (VII) ions are a strong oxidising agent, and in the first instance oxidise ethene to ethane-1,2-diol (old name: ethylene glycol). Looking at the equation purely from the point of view of the organic reaction: gold elephant candleWebIn alkenes, the high-electron density of the carbon-carbon double bond leads to attack on these molecules by electrophiles. Bromine reacts with alkenes, even though bromine is a non polar molecule.Explain why bromine molecules react with the double bonds in alkenes. Double bonds are electron rich. hcr housing voucherWebJan 23, 2024 · The reaction with bromine happens at room temperature. If you have a gaseous alkene like ethene, you can bubble it through either pure liquid bromine or a solution of bromine in an organic solvent like tetrachloromethane.
