Reaction of ethene with bromine water
WebEthene is an symmetrical alkene with two carbon atoms. With HBr, ethene readily reacts and give ethyl bromide (bromoethane) as the product. CH 2 =CH 2 + HBr → CH 3 CH 2 Br HBr molecule is added across the double bond of ethene. In this case, Markovnikov rule is not required because ethene molecule is symmetrical around the double bond. 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 is...

WebApr 9, 2016 · Explanation: Ethene and bromine are an addition reaction because ethene is an alkene - it has a double bond. It is easier for new atoms to open the double bond and … WebIn the case of the reaction with ethene, 1,2-dibromoethane is formed. This decolourisation of bromine is often used as a test for a carbon-carbon double bond. If an aqueous solution …
WebAs 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.

The reason is that there is no better proton acceptor present than CH 2 = CH 2 and no nucleophile good enough to combine with the cation. A Biological Hydration Reaction The conversion of fumaric acid to malic acid is an important biological hydration reaction.
