The synthesis of alkyl fluorides is best accomplished by:
1 Finkelstein reaction
2 Swarts reaction
3 Free radical fluorination
4 Sandmeyer's reaction
Explanation:
Alkyl fluorides are more conveniently prepared by heating suitable chloro- or bromoalkanes with organic fluorides such as \(\mathrm{AsF}_{3}, \mathrm{SbF}_{3}, \mathrm{CoF}_{2}, \mathrm{AgF}, \mathrm{Hg}_{2} \mathrm{~F}_{2}\) etc. This reaction is called Swarts reaction. \(\begin{aligned}& \mathrm{CH}_{3} \mathrm{Br}+\mathrm{AgF} \longrightarrow \mathrm{CH}_{3} \mathrm{~F}+\mathrm{AgBr} \\& 2 \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{Cl}+\mathrm{Hg}_{2} \mathrm{~F}_{2} \longrightarrow 2 \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{~F}+\mathrm{Hg}_{2} \mathrm{Cl}_{2}\end{aligned}\)

The reaction, \(2 \mathrm{R}-\mathrm{Cl}+\mathrm{CoF}_{2} \longrightarrow 2 \mathrm{R}-\mathrm{F}+\mathrm{CoCl}_{2}\), is an example of ____
1 Swarts reaction
2 Sandmeyer's reaction
3 Wurtz-fittig reaction
4 Finkelstein reaction
Explanation:
Given reaction is an example of Swart's reaction. It is an halogen exchange reaction associated with alkyl halides. In this reaction, a heavy metal fluoride is used. \(\mathop {{\rm{2R - Cl}}}\limits_{{\rm{Alkylchloride}}} {\rm{ + Co}}{{\rm{F}}_{\rm{2}}} \to \mathop {{\rm{2R - F}}}\limits_{{\rm{ Alkyl fluoride }}} {\rm{ + CoC}}{{\rm{l}}_{\rm{2}}}\) When alkyl chloride or alkyl bromide is heated with metallic fluoride \(\left(\mathrm{CoF}_{2}\right)\) then alkyl fluoride and corresponding metal chloride are produced.
