The products obtained after monochlorination of pentane and 3-methylpentane at 25 ° C should be written. Concept introduction: The monobromination performed with ultraviolet light proceeds via a radical chain mechanism. 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 the stability of radicals formed upon C – H bond cleavage via hyperconjugation. The phenomenon of hyperconjugation refers to the donation of σ electrons into the partly vacant p orbital lobes of radical carbon. More will be the number of σ orbital capable of donation of electrons more is the stabilization.
