Choose the correct answer from the options given below:

Options

  1. AA-I, B-IV, C-III, D-II
  2. BA-III, B-I, C-IV, D-II
  3. CA-IV, B-II, C-I, D-III
  4. DA-I, B-III, C-II, D-IV

Correct answer

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

Step-by-step solution

Finkelstein reaction involves the conversion of alkyl chlorides or bromides to alkyl iodides using NaINaI in dry acetone. Thus, A matches with III.

Swarts reaction is used for the synthesis of alkyl fluorides by heating an alkyl chloride or bromide in the presence of a metallic fluoride such as SbF3SbF_3, AgFAgF, Hg2F2Hg_2F_2, or CoF2CoF_2. Thus, B matches with I.

Sandmeyer's reaction involves the conversion of aryl diazonium salts to aryl halides using cuprous halides like Cu2Cl2Cu_2Cl_2 or Cu2Br2Cu_2Br_2. Thus, C matches with IV.

Fittig reaction involves the coupling of two aryl halide molecules in the presence of sodium (NaNa) and dry ether to form a diaryl compound. Thus, D matches with II.

The correct matching is A-III, B-I, C-IV, D-II.

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