Chapter 11, Problem 11.4P

Interpretation Introduction

(a)

Interpretation:

The mechanism and regioselectivity of the reaction is to be stated.

Concept introduction:

In the oxymercuration, when the aqueous solvent is replaced by an alcohol, then it is alkoxymercuration reaction. In the alkoxymercuration reaction, ether is formed. This process is called alkoxymercuration-reduction.

Interpretation Introduction

(b)

Interpretation:

The mechanism when an ether is synthesized by Williamson ether synthesis is to be stated.

Concept introduction:

The Williamson ether synthesis is the preparation of ether by the alkylation of an alkoxide. The Williamson ether synthesis is a ${\text{S}}_{\text{N}}2$ reaction. Tertiary and secondary halides do not participate in this reaction because they follow ${\text{S}}_{\text{N}}1$ reaction mechanism.
