Ethene react with bromine water
WebThe 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. The reddish-brown bromine is decolourised as it reacts with the alkene. WebEthene reacts with liquid bromine to give 1,2-dibromoethane. Ethene and bromine reaction also gives a symmetrical alkyl halide compound. Two bromine atoms are attached to the …

WebFor example, ethene reacts with bromine to form 1,2-dibromoethane: CH2=CH2 + Br2 → CH2BrCH2Br It is easier to see what happens using structures with all their covalent bonds : The reaction...
WebAn additional reaction happens between bromine and alkene. For instance, when ethene combines with bromine water, it forms 1, 2 dibromo ethanes. If the reactants are gaseous, the reaction must happen at room temperature (ethene). Even as bromine water solution combines with ethene, it loses its colour. breaklines in civil 3dWebIn the case of the reaction with ethene, 1,2-dibromoethane is formed.
