Question
Chapter 10, Problem 11PP
Interpretation Introduction
Interpretation: The allylic monobromo substitution products for the given compounds, the most stable isomeric product based on the double bond, and the resonance hybrid(s) for allylic radicals that are formed in each are to be discussed.
Concept introduction:
Molecules that have one unpaired electron are called free radicals.
A
Allylic bromination take place in the presence of NBS and peroxide or light. NBS is a good reagent for allylic bromination.

(3) HI does not undergo free radical addition with 1-butene, even in the presence
of a peroxide. Please provide an explanation by analyzing the propagation
steps if the same radical reaction occurred with HI. Besides the bond
dissociation enthalpies in the appendix, the following approximate bond
dissociate enthalpies might be useful to you:
