Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Swarts reaction is used to prepare alkyl fluorides by replacing halogen atoms (Cl/Br) with fluorine using metal fluorides like $\mathrm{AgF}$, $\mathrm{SbF_3}$, etc.
Step 1: Identify reaction type.
\[ \mathrm{CH_3Br + AgF \rightarrow CH_3F + AgBr} \] Halogen exchange: Br replaced by F
Step 2: Name the reaction.
This halogen exchange using metal fluoride is called Swarts reaction.
