JEE MainChemistryHaloalkanes and Haloarenes
Which of the following reactions is NOT correctly matched with its name?
Options
- AR - Br + AgF R - F + AgBr : Swarts reaction
- BC ₆ H ₅ Br + CH ₃ Br + 2 Na Dry ether C ₆ H ₅ CH ₃ + 2 NaBr : Wurtz-Fittig reaction
- CR - Cl + NaI Dry acetone R - I + NaCl : Finkelstein reaction
- DC ₆ H ₅ N ₂^+ Cl ^- Cu ₂ Cl ₂/ HCl C ₆ H ₅ Cl + N ₂ : Gatterman reaction
Correct answer
D. C ₆ H ₅ N ₂^+ Cl ^- Cu ₂ Cl ₂/ HCl C ₆ H ₅ Cl + N ₂ : Gatterman reaction
Step-by-step solution
Let us evaluate each option: Option 1 represents the synthesis of alkyl fluorides by heating an alkyl chloride/bromide in the presence of a metallic fluoride such as AgF . This is correctly known as the Swarts reaction. Option 2 involves the reaction of an aryl halide and an alkyl halide with sodium in dry ether to give an alkylarene. This is correctly known as the Wurtz-Fittig reaction. Option 3 represents the reaction of an alkyl chloride with sodium iodide in dry acetone to form an alkyl iodide. This halogen exc
