Chapter 25, Problem 25.12P

Interpretation Introduction

Interpretation:

The three possible ${\text{S}}_{\text{H}}\text{2}$ steps, including curved arrows, which can occur between

$\text{Cl}·$ and ethane are to be drawn.

Concept introduction:

In bimolecular homolytic substitution (${\text{S}}_{\text{H}}\text{2}$) step, a free radical forms a new bond to an atom, causing another bond to that atom to break. In the process, a new free radical is displaced from that atom. Three single barbed curved arrows are used to show the bond breaking and bond forming.
