Chapter 26, Problem 26.6YT

Interpretation Introduction

(a)

Interpretation:

Using Figures $\text{26-8}$ and $\text{26-9}$ as guides, the combination step involving two of the final radicals shown in Solved Problem $\text{26}\text{.4}$ is to be drawn.

Concept introduction:

The combination of two or more elements (radicals) to form one compound is called combination reaction. A combination reaction is a reaction where two or more elements (radicals) or compounds (reactants) combine to form a single compound (product). Such reactions may be represented by equations of the following form: $\text{X + Y}\to \text{XY}$.

Interpretation Introduction

(b)

Interpretation:

Using Figures $\text{26-8}$ and $\text{26-9}$ as guides, the disproportionation step involving two of the final radicals shown in Solved Problem $\text{26}\text{.4}$ is to be drawn.

Concept introduction:

Radical disproportionation encompasses a group of reactions in organic chemistry in which two radicals react to form two different non-radical products. Due to the unstable nature of radical molecules, disproportionation proceeds rapidly and requires little to no activation energy. The most thoroughly studied radical disproportionation reactions have been conducted with alkyl radicals, but there are many organic molecules that can exhibit more complex, multi-step disproportionation reactions.
