How will you prepare Alkyl halide from halogen exchange?

1.	How will you prepare Alkyl halide from halogen exchange?
Answer» Alkyl halide from halogen exchange: In this reaction, alkyl halides are prepared from alkyl halides only. For Example: R – Cl + Nal \(\overset{\Delta}{\underset{Acetone}{\longrightarrow}}\) R – I + NaCl R – Br + Nal \(\overset{\Delta}{\underset{Acetone}{\longrightarrow}}\) R – I + NaBr This reaction is known as the Finkelstein reaction. The synthesis of alkyl fluoride is best accomplished by heating alkyl iodide in the presence of a metallic fluoride such as AgF. This reaction is called “Swarts reaction”. R – I + AgF → R -F + Agl
