Question

The synthesis of alkyl fluorides is best accomplished by:

• A. Swarts reaction
• B. Free radical fluorination
• C. Sandmeyer's reaction
• D. Finkelstein reaction

Answer 1

Answer: (A)

Alkyl fluorides is best accomplished by swarts reaction i.e. heating an alkyl chloride/bromide in the presence of metallic fluoride such as AgF, Hg₂F₂, CoF₂, SbF₃.
${\text{CH}}_3\text{Br}+\text{AgF}\to {\text{CH}}_3\text{F}+\text{AgBr}$
