The synthesis of alkyl fluorides is best accomplished by :

Options

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

Answer

B

Explanation

Alkyl fluorides are more conveniently prepared by heating suitable chloro - or bromo - alkanes with organic fluorides such as ` AsF _ 3, Sb F _ 3, Co F _ 2 , AgF, Hg _ 2 Fe _ 2 ` etc. This reaction is called swarts reaction.
`CH _ 3 B r + AgF to CH _ 3 F + Ag B r `
` 2 CH _ 3 CH _ 2 Cl + Hg _ 2 F _ 2 to 2 CH _ 3 CH _ 2 F + Hg _ 2 Cl _ 2 `
