Ketone

Vedclass · Answer

(B) The reaction of an alkyl cyanide $(R-CN)$ with a Grignard reagent $(R'-MgX)$ proceeds as follows:$1$. Nucleophilic attack of the Grignard reagent on the carbon atom of the cyanide group forms an imine intermediate: $R-C \equiv N + R'-MgX \rightarrow R-C(R')=N-MgX$.$2$. Subsequent acid hydrolysis of this intermediate yields a ketone: $R-C(R')=N-MgX + H_2O \rightarrow R-CO-R' + NH_3 + Mg(OH)X$.Therefore,the final product obtained is a ketone.

Alkyl cyanides,when reacted with a Grignard reagent followed by hydrolysis,yield which of the following products?
