Vedclass · Answer

(C) The reaction is as follows:$CH_3Cl + KCN_{(alc)} \xrightarrow{\Delta} CH_3CN (A) + KCl$$CH_3CN + 2H_2O \xrightarrow{HCl} CH_3COOH (B) + NH_4Cl$In the first step,chloromethane reacts with alcoholic $KCN$ to form ethanenitrile $(CH_3CN)$,which is compound $A$.In the second step,the acid hydrolysis of ethanenitrile yields ethanoic acid $(CH_3COOH)$,which is compound $B$.Therefore,$A =$ Ethanenitrile and $B =$ Ethanoic acid.

Identify the compounds $A$ and $B$ in the following reaction.
