Question

How will you prepare methoxyethane from alkyl halide?

Answer 1

Explanation :

This reaction is called as williamson ether synthesis in which an alkoxide ion react with the alkyl halide via $S_N2$ reaction.

Preparation of Methoxy-ethane :

In this reaction, a nucleophile (Sodiumethoxide) react with an electrophile (Methylbromide) to form Methoxymethane by the substitution reaction.

During the reaction, one carbon-oxygen bond formed and one carbon-halogen bond broken.

Answer 2

You can prepare the methoxyethane from an alkyl halide, and the explanation is given below:

Unlike the diethyl ether, methoxyethane is not a symmetrical molecule. Because of this, there will be two C-O bonds available for you in the SN2 reaction which will help you to generate the ether.  

By using the reverse-synthesizing process, bonds will get broken, and methoxyethane will get prepared from the alkyl halide.
