Question

Match List-I with List-II.

Choose the correct answer from the options given below :

• A. (A)-(III), (B)-(II), (C)-(I), (D)-(IV)
• B. (A)-(IV), (B)-(II), (C)-(III), (D)-(I)
• C. (A)-(I), (B)-(IV), (C)-(II), (D)-(III)
• D. (A)-(II), (B)-(IV), (C)-(I), (D)-(III)

Answer 1

The Correct Option is D

To solve the problem, we need to match the reactions in List-I with the correct products from List-II based on well-known organic chemistry reactions. Let's go through each reaction step-by-step:

1. (A) Reaction: Benzene with an amino group (NH₂) is treated with NaNO₂ + HCl followed by warm H₂O. This is a well-known diazotization reaction that converts aniline to phenol. In this case, however, it forms a benzene with an aldehyde at the para position. Thus, this matches with (II).
2. (B) Reaction: Phenol (OH group) is oxidized by Na₂Cr₂O₇ / H₂SO₄. This oxidizes the alcohol to a carboxylic acid. Therefore, the product is benzoic acid (with the carboxylic group), which matches with (IV).
3. (C) Reaction: Phenol is treated with CHCl₃ + aq NaOH followed by H⁺. This is the Reimer-Tiemann reaction, which forms salicylic acid (with a carboxyl group adjacent to the phenol group). Thus, this matches with (I).
4. (D) Reaction: Phenol is treated with NaOH, then CO₂, and finally H⁺. This results in the Kolbe-Schmitt reaction, forming salicylic acid (with the carboxyl group para to the phenol group). This corresponds with (III).

Thus, the correct matching is (A)-(II), (B)-(IV), (C)-(I), (D)-(III). This matches the provided correct answer.
