Options
- AA-I, B-IV, C-III, D-II
- BA-III, B-I, C-IV, D-II
- CA-IV, B-II, C-I, D-III
- 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 NaI 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 SbF₃ , AgF , Hg₂F₂ , or CoF₂ . Thus, B matches with I. Sandmeyer's reaction involves the conversion of aryl diazonium salts to aryl halides using cuprous halides like Cu₂Cl₂ or Cu₂Br₂ . Thus, C matches with IV. Fittig reaction
