Pentene reaction with bromine

WebThe reaction between a C=C double bond and bromine (Br2) can be used as a test for the presence of alkene in an unknown sample. The bromine reagent is in a reddish color, and the product vicinal dibromide is colorless. When bromine is added to the sample, if the reddish color disappears, it means the sample contains an alkene. WebIn the halogen substitution reaction of alkanes, there are two main factors to consider: how energetic the reaction is and the magnitude of the activation energy. The reaction of fluorine with methane releases a lot of energy, much more than the reactions of chlorine and bromine. The reaction with iodine, on the other hand, requires energy.
