Correct answer
BA-III, B-I, C-IV, D-II
Step-by-step explanation
Finkelstein reaction involves the conversion of alkyl chlorides or bromides to alkyl iodides using 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 , , , or . Thus, B matches with I.
Sandmeyer's reaction involves the conversion of aryl diazonium salts to aryl halides using cuprous halides like or . Thus, C matches with IV.
Fittig reaction involves the coupling of two aryl halide molecules in the presence of sodium () 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
