The Correct Option is A
Solution and Explanation
Step 1: Understanding the Reaction Sequences
- (P) Ozonolysis followed by base-induced rearrangement and protection
- The reaction sequence cleaves a benzene ring, forming a six-membered hydroxy-containing ring.
- Matches: (3)
- (Q) Ozonolysis, protection, and hydroboration-oxidation
- Leads to hydroxylation and the introduction of a methyl group.
- Matches: (5)
- (R) Hydration followed by reduction
- Produces a hydroxy-substituted five-membered ring with a retained carbonyl group.
- Matches: (4)
- (S) Hydroboration-oxidation followed by reduction
- Converts the five-membered ring into a hydroxyl-functionalized product.
- Matches: (1)
Step 2: Conclusion
- (P) → (3)
- (Q) → (5)
- (R) → (4)
- (S) → (1)
Thus, the correct answer is (A) P-3, Q-5, R-4, S-1.

- A thin stiff insulated metal wire is bent into a circular loop with its two ends extending tangentially from the same point of the loop. The wire loop has mass \( m \) and radius \( r \) and is in a uniform vertical magnetic field \( B_0 \). When a current \( I \) is passed through the loop, the loop turns about the line PQ by an angle \( \theta \). The angle \( \theta \) is given by:

- A region in the form of an equilateral triangle (in x-y plane) of height \( L \) has a uniform magnetic field \( \mathbf{B} \) pointing in the \( +z \)-direction. A conducting loop PQR, in the form of an equilateral triangle of the same height \( L \), is placed in the x-y plane with its vertex \( P \) at \( x = 0 \) in the orientation shown in the figure. At \( t = 0 \), the loop starts entering the region of the magnetic field with a uniform velocity \( \mathbf{v} \) along the \( +x \)-direction. The plane of the loop and its orientation remain unchanged throughout its motion.
