Question

Give two methods for the preparation of the ether?​

Answer 1

Answer:

Ethers can be prepared from other organic compounds by numerous methods. Some of them are underlined below:

Dehydration of alcohols: In the presence of sulphuric acid, dehydration of ethanol yields ethoxyethane at 413 K. This is an ideal method of preparation through primary alcohols. Preparation of ethers by dehydration of an alcohol is a nucleophilic substitution reaction.

Answer 2

formation of ether by alcohol :-

primary alcohol undergoes intermolecular dehydration when heated with conc sulphuric acid to form ether

formation of ether from alkyl halide :-

sodium and potassium alkoxide react with alkyl halide to form ether .

formation of ether from dizomethane :-

alcohol react with dizomethane to form methyl ether .
