Which among the following reactions is used for the preparation of alkyl fluorides?
Finkelstein reaction
Swartz reaction
Fittig reaction
Wurtz reaction
Solution
Alkyl fluorides are prepared by heating alkyl chlorides or bromides with metal fluorides such as $\mathrm{AgF}, \mathrm{Hg}_2 \mathrm{~F}_2, \mathrm{AsF}_3, \mathrm{SbF}_3$, etc. This reaction is known as Swartz reaction.
$\mathrm{R}-\mathrm{Cl}+\mathrm{AgF} \longrightarrow \mathrm{R}-\mathrm{F}+\mathrm{AgCl} \downarrow$
