WebUsing bromine water as a test for alkenes If you shake an alkene with bromine water (or bubble a gaseous alkene through bromine water), the solution becomes colourless. …
WebAs bromine addition to ethene, propene and bromine reaction occurs in same way. First, Br 2 molecule is polarized by alkene bond. With that, electrons in the double bond attacks the positively charged Br atom and forms a cyclic bromonium ion. Other Bromine atom is eliminated as a bromide ion. As second step, produced bromide ion attacks a ... 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 …
