Poor selectivity in the formation of the brominated products when equimolar mixture of Br 2 and Cl 2 compared to the case when Br 2 alone is taken should be explained. Concept introduction: The monobromination performed with ultraviolet light proceeds via radical chain mechanism. In general, tertiary C – H bonds react in halogenations more readily than secondary those, in turn, are faster to react than primary. This can be attributed to stability of radical formed upon C – H bond cleavage via hyperconjugation. The phenomenon of hyperconjugation refers to donation of σ electrons into the partly vacant p orbital lobes of radical carbon. More will be number of σ orbital capable of donation of electrons more is the stabilization.
