Chemistry - ORGANOMETALLIC COMPOUNDS Question with Solution | TestHub

Question Explanation:

Nitrile is treated with 1.0 equivalent of ${\mathrm{C}}_6{\mathrm{H}}_5\mathrm{MgBr}$ in dry ether followed by acid workup; identify the major product X.

Concept:

This question is based on reaction of Grignard reagent with $\mathrm{R}-\mathrm{C}\equiv \mathrm{N}$ and acidic hydrolysis.

Solution:

One equivalent of a Grignard reagent adds to a nitrile to give an imine- Mg salt which upon acidic hydrolysis yields a ketone.

Final Answer: Option (D)
