Chapter 25, Problem 25.64P

Interpretation Introduction

Interpretation:

In the problem 25.63, the hydroperoxide forms at the C atom that is alpha to the O atom and not at the one that is beta to it is to be explained.

Concept introduction:

A free radical chain reaction involves free radicals in a cyclic sequence of steps, called propagation steps, which are responsible for converting overall reactants into overall products. An initiation step is responsible for producing the free radical that enters the propagation cycle. A termination step removes free radicals from the propagation cycle and is responsible for slowing the overall reaction. Oxygen is a diradical, so it can abstract a $\text{H}$ atom to generate the initial radical that enters the propagation cycle.
