WebHalogenation of Alkenes Mechanism. Step 1: The pi electrons of the alkene attack one of the bromine atoms which attacks one the of the alkene carbons back forming a three-membered ring with Br referred to as a bromonium ion (generically referred to as a halonium ion and specifically a chloronium ion in the reaction with Cl2). WebAug 20, 2024 · 1 Answer. With bromination, the first step is the formation of an adduct complex, which can be explained that the π-bond polarises the dibromide. The next step is the formation of the bromonium ion, which …

WebJun 17, 2024 · The reaction goes by a radical mechanism when a peroxide is present. The first step is the homolysis (homolytic cleavage) of the RO-OR bond: The resulting radical reacts with HBr by abstracting the H and a new radical Br• is formed: After this, a regioselective addition of the Br to the alkene happens. It is regioselective because the … ninja warrior leeds seacroftWebThe product formed after bromination displays completely different properties from the initial reactant molecule.
