Which of the following reactions is used for the preparation of alkyl fluorides from alkyl chlorides?

Step-by-step solution

Swarts reaction is the standard method used for the preparation of alkyl fluorides from alkyl chlorides or bromides. In this reaction, heating an alkyl chloride or bromide in the presence of a metallic fluoride such as AgF , Hg₂F₂ , CoF₃ , or SbF₃ yields the corresponding alkyl fluoride. R-Cl + AgF R-F + AgCl Finkelstein reaction is used for the preparation of alkyl iodides. Sandmeyer's reaction is used for the preparation of aryl halides from diazonium salts. Fittig reaction is used for the preparation of diaryls
