Question

Allylic bromination of alkenes is accomplished with the reagent NBS (N-bromosuccinimide). The reaction proceeds by a radical chain mechanism. For the following reaction: NBS Br light, CCI4 a Select the species that you would expect to react in the first propagation step and draw curly arrows to show the mechanism. Use half-headed (fishhook) curved arrows to show electron reorganization. When drawing bond formation by pairing of single electrons, terminate the arrows in a hotspot located to one side of a reacting radical. This hotspot is not associated with any structural feature.
