The structure of X is :
The structure of X is :
Show Hint
The Correct Option is C
Solution and Explanation
Step (i): \(\mathrm{C_6H_5MgBr}\) (1 equivalent, dry ether) adds across the C\(\equiv\)N bond, giving the magnesium salt of a ketimine: Ar-C(=NMgBr)-C\(_6\)H\(_5\).
Step (ii): \(\mathrm{H_3O^+}\) hydrolyses the imine to the ketone, Ar-CO-C\(_6\)H\(_5\), with loss of NH\(_3\).
The benzylic methyl ether is not touched under these conditions. So X is the benzophenone derivative bearing the CH(CH\(_3\))OCH\(_3\) group ortho to the C=O, which is option (3).
Answer: (3) ketone with C=O-C\(_6\)H\(_5\) and CH(CH\(_3\))OCH\(_3\) substituents (structure as drawn)

Top JEE Main Questions
- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
