alleryThe reaction of alkyl chloride/bromide with NaI in dry acetone to form alkyl iodide is called:
AWurtz reaction
BFinkelstein reaction
CSwarts reaction
DSandmeyer reaction
Answer & Solution
Correct answer: B. Finkelstein reaction
**Finkelstein reaction**: R-X + NaI
→ R-I + NaX (X = Cl, Br) in **dry acetone**.
NaCl/NaBr precipitates out (insoluble in acetone)
→ drives equilibrium forward via Le Chatelier.
**Swarts reaction** (R-X + AgF → R-F) makes fluorides.
