Chapter 25, Problem 25.35P

Interpretation Introduction

(a)

Interpretation:

The curved arrow notation and product for the given reaction which undergoes ${\text{S}}_{\text{H}}\text{2}$ step is to be drawn.

Concept introduction:

In an ${\text{S}}_{\text{H}}\text{2}$ step, H atoms or halogen atoms are abstracted, similar dynamics as ${\text{S}}_{\text{N}}\text{2}$ reaction. Single-barbed curved arrows are used to show movement of single electrons and this is thing differ ${\text{S}}_{\text{H}}\text{2}$ reaction from ${\text{S}}_{\text{N}}\text{2}$ reaction. Three Single-barbed curved arrows are used to represent the step: two Single-barbed curved arrows (in opposite direction) originating from the middle of C-H bond which is going to break and one is originating from the radical end to the atom which is abstracted by the radical.
