Chapter 25, Problem 25.31P

Interpretation Introduction

Interpretation:

The curved arrow notation for the given elementary step is to be added. The step is to be classified as homolysis, radical coupling, ${\text{S}}_{\text{H}}\text{2}$ or radical addition.

Concept introduction:

A single-barbed arrow is used to show the movement of a single electron in an elementary step. If one radical displaces by other radical similar in ${\text{S}}_{\text{N}}\text{2}$ one nucleophile is substituted by other, correlates ${\text{S}}_{\text{H}}\text{2}$ step.
