Match List - I with List - II. Choose the correct answer from the options given below :

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

Answer

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

Solution

As per NCERT, the C–Cl bond in chlorobenzene has partial double-bond character, so replacement of Cl by OH needs drastic conditions. -NO2 groups at ortho/para positions withdraw electron density and stabilise the carbanion intermediate, so the reaction becomes easier as their number increases:

(A) Chlorobenzene → phenol: NaOH, 623 K, 300 atm, then H3O+ → IV

(B) 4-Nitrochlorobenzene → 4-nitrophenol: NaOH, 443 K, then H3O+ → III

(C) 2,4-Dinitrochlorobenzene → 2,4-dinitrophenol: NaOH, 368 K, then H3O+ → II

(D) 2,4,6-Trinitrochlorobenzene → picric acid: warm water → I

A-IV, B-III, C-II, D-I

Answer: (4)
