(a)

Interpretation Introduction

Interpretation:

The family of organic compound is to be determined using functional group.

Concept introduction:

There are various functional groups in organic compounds.

Functional group	General formula
Halogen	$\text{R}-\text{X}$
Alcohol	$\text{R}-\text{O}\text{H}$
Carboxylic acid	$\text{R}-\text{C}\text{O}\text{O}\text{H}$
Aldehydes	$\text{R}-\text{C}\text{H}\text{O}$
Ketones	$\text{R}\text{C}\text{O}{\text{R}}^{\text{'}}$
Esters	$\text{R}\text{C}\text{O}\text{O}{\text{R}}^{\text{'}}$
Amines	$\text{R}-\text{N}{\text{H}}_2$
Ethers	$\text{R}-\text{O}-{\text{R}}^{\text{'}}$

Answer to Problem 40A

Ether

Explanation of Solution

The general formula of given compound is $\text{R}-\text{O}-{\text{R}}^{\text{'}}$
