Chapter 23.9, Problem 8P

Interpretation Introduction

Interpretation:

Thestructures for appropriate phenol and alkyl halide from which the given aryl ethers can be prepared are to be suggested.

Concept introduction:

The phenol is a functional group in which the aromatic ring is directly bonded to hydroxyl group.

In alky halide, the halogen atom is bonded to alkyl group and represented as $\text{R-X}$, where $\text{R}$ is an alkyl group and $\text{X}$ is the halogen atom.

The phenol in the presence of a base is converted to a phenoxide ion, which, is on reaction with alkyl halide, undergoes $\text{O-alkylation}$ through substitution reaction and forms aryl ether.

In aryl ether, the oxygen attached to the aromatic ring is a part of phenol, and the alkyl group bonded to oxygen, which is directly attached to the aromatic ring, is a part of alkyl halide.
