Question

how will you prepare ethanoic acid by ethanenitrile

Answer 1

Answer:

H+

CH3CN+H2O----->CH3COOH

You can convert acetonitrile (ethanenitrile) to acetic acid by acid hydrolysis - reflux the nitrile with dilute hydrochloric acid, and you will form the acetic acid which can then be distilled off.

Answer 2

Preparing Ethanoic acid from ethanenitrile

Explanation:

Ethanoic acid

It is a member of carboxylic acid .

Its molecular formula is CH₃COOH

Ethanenitrile

It has a cyano group .

its molecular formula is CH₃CN

Any carboxylic acid member can be prepared from methyl nitrile by reacting it with water to form amide and then carrying out its hydrolysis to form carboxylic acid .

The general reaction involved is :

RCN +H₂O ---> RCONH₂ ----------> RCOOH

methylnitrile      amide             H⁺       carboxylic acid

For preparing ethanoic acid we have :

CH₃CN +H₂O-------> CH₃CONH₂ ------------> CH₃COOH

                       H⁺                             H₂O
