Answer: a) dehydration reaction is the correct answer.

Explanation:

When excess of ethyl alcohol is heated with concentrated sulphuric acid, diethyl ether is obtained.

This is distillation process

Reaction takes place at 413K

Reaction is as follows:

2C2H5-OH=====> C2H5-O-C2H5+H2O

C2H5-O-C2H5 is diethyl ether.

In this reaction, equal amount of alcohol and concentrated sulphuric acid are taken in a distillation flask.

Step 1

The ethyl alcohol reacts with acid to give ethyl hydrogen sulphate

Step 2

Excess ethyl alcohol is added to the flask.

Ethyl hydrogen sulphate reacts with added alcohol to give diethyl ether.

C2H5-SO3H is ethyl hydrogen sulphate.

This is dehydration reaction and also known as continuous etherification reaction.

This method is best suited with the help of primary alcohols.
