Did you know?
WebA chain reaction mechanism for the chlorination of methane has been described. Bromination of alkanes occurs by a similar mechanism, but is slower and more selective because a bromine atom is a less reactive hydrogen abstraction agent than a chlorine atom, as reflected by the higher bond energy of H-Cl than H-Br. WebChlorination Step 1: formation of a chloronium ion Step 2: attack of the chloronium ion on the ring + + + Resonance-stabilized cation intermediate; the positive charge is delocalized …
