Vedclass · Answer

(B) The abstraction of a hydrogen atom by a bromine free radical $(Br^{\cdot})$ depends on the stability of the resulting free radical intermediate.More stable free radicals are formed more easily.The hydrogen at position $(b)$ is a benzylic hydrogen.Abstraction of this hydrogen leads to the formation of a benzylic free radical,which is highly stabilized by resonance with the benzene ring.Therefore,the hydrogen at position $(b)$ is the most easily abstracted.

Which of the following hydrogens is most easily abstracted on reaction with bromine free radicals,$Br^{\cdot}$?
