Match List-I with List-II. List-I (Conversion) (A) Chlorobenzene → Phenol (B) Chlorobenzene having NO2 group at meta position → Phenol having NO2 group at meta position List-II (Reagents, Conditions used) (I) Warm, H2O (II) (a) NaOH, 368 K; (b) H3O+

1. (A)-(I), (B)-(II), (C)-(I), (D)-(IV)
2. (A)-(IV), (B)-(III), (C)-(II), (D)-(I)
3. (A)-(IV), (B)-(III), (C)-(I), (D)-(II)
4. (A)-(II), (B)-(IV), (C)-(I), (D)-(I)

Correct answer: (A)-(IV), (B)-(III), (C)-(II), (D)-(I)

Solution

The conversion of chlorobenzene to phenol requires strong conditions, which is achieved using sodium hydroxide at high temperature (368 K) followed by acidification, making option (A)-(IV) correct. For the second conversion, the presence of the nitro group directs the reaction to maintain its position, which is accomplished through hydrolysis under acidic conditions, aligning with option (B)-(III).
