Chapter 9, Problem 9.30P

Interpretation Introduction

(a)

Interpretation: The alkyl halides formed by the treatment of given ether with $\text{HBr}$ are to be stated.

Concept introduction: Ethers react with strong acids, (only $\text{HBr}$ and $\text{HI}$) and yield two alkyl halides as products.

$\begin{array}{l}\text{R}-\text{O}-{\text{R}}^{\text{'}}\underset{2\text{equivalents}}{\overset{\text{HX}}{\to }}\text{R}-\text{X}+{\text{R}}^{\text{'}}-\text{X}+{\text{H}}_{\text{2}}\text{O}\\ \text{X}=\text{Br}\text{or}\text{I}\end{array}$

In this reaction, both $\text{C}-\text{O}$ bonds of ether are cleaved by two successive nucleophilic substitution reactions.
