The synthesis of alkyl fluorides is best accomplished by

free radical fluorination

Sandmeyer's reaction

Finkelstein reaction

Swarts reaction

Solution

Swarts reaction

Alkyl fluorides can be prepared by the action of mercurous fluorides or antimony trifluoride (inoragnic fluorides) on corresponding alkyl halide.
This reaction is known as Swarts reaction
CH₃Br + AgF → CH₃F + AgBr
But, when the action of NaI/acetone takes place on alkyl chloride or bromide alkyl iodide forms. This reaction is called 'Finkelstein reaction.

Free radical fluoridation is a highly explosive reaction. So not preferred for the preparation of fluoride.
