The major product obtained in the following reaction is :
Show Hint
The Correct Option is D
Solution and Explanation
LiAlH4 (excess) reduces: -COOH to -CH2OH; the ketone C=O to a secondary alcohol -CH(OH)CH3; the aliphatic nitro group to -NH2.
It does not reduce an isolated C=C bond, so the vinyl group remains.
Product: ring with -CH2OH, -CH=CH2, -CH(OH)CH3 and -NH2, which is option (4).
Answer: (4) the amino diol with the vinyl group retained (CH2OH, NH2, CH(OH)CH3, CH=CH2)

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:
