Question

List-I contains various reaction sequences and List-II contains different phenolic compounds. Match each entry in List-I with the appropriate entry in List-II and choose the correct option.

List I		List II
(P)		(1)
(Q)		(2)
(R)		(3)
(S)		(4)
		(5)

• A. P-2, Q-3, R-4, S-5
• B. P-2, Q-3, R-5, S-1
• C. P-3, Q-5, R-4, S-1
• D. P-3, Q-2, R-5, S-4

Answer 1

The Correct Option is C

Step 1: Understanding the Reaction Sequences 

• (P) Fusion of benzenesulfonic acid with molten NaOH followed by nitration
  • Leads to Trinitrophenol (Picric acid).
  • Matches: (3)
• (Q) Nitration followed by diazotization and hydrolysis
  • Forms 2,4,6-Trinitrophenol.
  • Matches: (5)
• (R) Sulfonation, nitration, and hydrolysis
  • Produces Dinitrophenol.
  • Matches: (4)
• (S) Oxidation of methylbenzene, nitration, bromination, and hydrolysis
  • Forms Nitrohydroxybenzene.
  • Matches: (1)

Step 2: Conclusion

• (P) → (3)
• (Q) → (5)
• (R) → (4)
• (S) → (1)

Thus, the correct answer is (C) P-3, Q-5, R-4, S-1.

Answer 2

To solve the problem, we need to analyze each reaction sequence and match it with the correct phenolic compound product.

1. For (P):
- Sulfonation of benzene sulfonic acid followed by nitration.
- The sulfonic group is replaced by hydroxyl (via molten NaOH and acidification).
- Final product is Trinitrophenol.
- Corresponds to structure (3).

2. For (Q):
- Nitration of nitrobenzene, reduction, diazotization, and further nitration.
- Final product is 2,4,6-trinitrophenol (picric acid).
- Corresponds to structure (5).

3. For (R):
- Nitration of hydroquinone (1,4-dihydroxybenzene).
- Final product is 2,5-dinitrohydroquinone.
- Corresponds to structure (4).

4. For (S):
- Multiple steps starting from toluene, oxidation, nitration, bromination, diazotization.
- Final product is 2,4-dinitrophenol.
- Corresponds to structure (1).

Final Matching:
P - 3, Q - 5, R - 4, S - 1

Final Answer:
Option (C)
