Question

Why we do not use chlorine instead of bromine in h.V.Z. Reaction?

Answer 1

Answer:

a 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.bcoz of this reason bromine is used
