Which method is most suitable for preparing alkyl fluorides?

1. Finkelstein reaction
2. Swarts reaction
3. Free-radical fluorination
4. Sandmeyer reaction

Correct answer: Swarts reaction

Solution

The Swarts reaction treats an alkyl chloride/bromide with a metallic fluoride (AgF, Hg2F2, CoF2, SbF3) to give the alkyl fluoride, e.g. CH3Br + AgF -> CH3F + AgBr. Free-radical fluorination is too violent/uncontrolled to be useful.
