Chapter 9.4, Problem 11P

(a)

Interpretation Introduction

Interpretation:

The reason should be explained for difficulty in the synthesis of unsymmetrical ether.

Concept introduction:

Ethers:

An oxygen atom connected to two alkyl or aryl groups is called as ether. The general formula of ether is $\text{R–O–R'}$ where R and R′ group either alkyl or aryl groups.

Ethyl alcohol is reaction with acid which yields diethyl ether which is shown below.

(b)

Interpretation Introduction

Interpretation:

The ethyl propyl ether should be synthesized.
