WebJan 23, 2024 · Alkenes decolorize bromine water. If you shake an alkene with bromine water (or bubble a gaseous alkene through bromine water), the solution becomes colorless. This is complicated by the fact that the major product is not 1,2-dibromoethane. The water also gets involved in the reaction, and most of the product is 2-bromoethanol. WebJan 23, 2024 · The carbon-carbon double bond in alkenes such as ethene react with concentrated sulfuric acid. It includes the conversion of the product into an alcohol. ... This is called halogenation. Reactions where the chlorine or bromine are in solution (for example, "bromine water") are slightly more complicated and are treated separately at the end ...

WebMay 29, 2024 · The equation for the reaction of ethene and bromine is: C2H4(g) + Br2(l) C2H4Br2(l) The reaction is exothermic. Is Hydrohalogenation an addition reaction? … pittelkow
1,2-dibromoethane - an overview ScienceDirect Topics
WebAlkenes react in the cold with pure liquid bromine, or with a solution of bromine in an organic solvent like tetrachloromethane. The double bond breaks, and a bromine atom becomes attached to each carbon. The bromine loses its original red-brown colour to give a colourless liquid. WebMay 12, 2014 · The mechanism is analogous to the addition of bromine to ethene, which is nicely described at chemguide.co.uk. The essential part is the attack of the bromine at the HOMO (s). The ring opening reaction can be reversed by adding sodium. However, when there are bromine radicals present (UV light) then substitution will occur: WebC=C, allows alkenes to undergo addition reactions. For example, ethene reacts with water (in the presence of heat and a catalyst) to produce the alcohol ethanol. pitte ki pathri ka ilaj
