The correct statement about (A), (B), (C) and (D) is:
The correct statement about (A), (B), (C) and (D) is:
Show Hint
- (A), (B) and (C) are narcotic analgesics
- (B), (C) and (D) are tranquilizers
- (A) and (D) are tranquilizers
- (B) and (C) are tranquilizers
The Correct Option is D
Solution and Explanation
The question identifies specific pharmacological classes of given chemical structures.
Step 2: Detailed Explanation:
(A) Structure (A) is Morphine. Morphine is a classic narcotic analgesic used for severe pain relief.
(B) Structure (B) is Diazepam (Valium). It belongs to the class of benzodiazepines, which are tranquilizers used for anxiety and sleep disorders.
(C) Structure (C) is Serotonin (or a related derivative like Valium-like neurotransmitter components). In the context of medicinal chemistry textbooks (like NCERT), structures like Valium and Serotonin/derivatives are associated with tranquilizers or mood regulation.
(D) Structure (D) is Codeine. It is a derivative of morphine and is also classified as a narcotic analgesic.
Step 3: Final Answer:
Since (B) is Diazepam and (C) is related to neurological mood management, they are classified as tranquilizers. (A) and (D) are narcotic analgesics. Thus, option (D) is the only correct grouping.

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:
