Answer :
Final answer:
The product of the reaction between a Grignard reagent and a nitrile, followed by acid hydrolysis, is a ketone. The Grignard reagent adds to the electrophilic carbon of the nitrile, forming an imine salt, which is then hydrolyzed to produce the ketone.
Explanation:
The reaction of a Grignard reagent with a nitrile like acetonitrile results in the formation of an imine salt. Initially, the Grignard reagent adds to the electrophilic carbon of the nitrile. The resulting imine salt can then undergo acid hydrolysis to yield a ketone. This transformation occurs because Grignard reagents act as nucleophiles and the carbon in a nitrile group is electrophilic.
Upon hydrolysis of the imine intermediate, a ketone is formed. For example, when a Grignard reagent such as CH2MgI, reacts with nitriles, the final product after hydrolysis is typically RCOCH3 where R represents the organic group attached to the nitrile carbon.
