Chapter 4, Problem 50Q

(a)

Interpretation Introduction

Interpretation:

Lewis structure of dimethyl ether has to be drawn.

Concept introduction:

Electron-dot (Lewis) symbol: The numbers of valence electron are shown using dot symbol around the atomic symbol.

The valance electrons are represented as a dot; the dots are distributed around the four sides of the element symbol.  Primarily, fill electrons in each side of the atomic symbol, if the element has five or more than five electrons, the electrons are added in the four sides of the element symbol then it will get paired.  The maximum dot of the electron in one side of the element symbol is two.

(b)

Interpretation Introduction

Interpretation:

The structure of diethyl ether has to be drawn and number carbon is calculated in diethyl ether.

(c)

Interpretation Introduction

Interpretation:

Interpretation:

A common structural feature of ether has to be explained.

Concept introduction:

Ethers:

An oxygen atom connected to two alkyl or aryl groups is called as ether. The general formula of ether is 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.
