Question

A mixture of alkyl halide and aryl halide with sodium in dry ether. What is the name of reaction?

• A. Fittig reaction
• B. Finkelstein reaction
• C. Wurtz-Fittig reaction
• D. Wurtz reaction

Hint:

Remember these three related name reactions easily: alkyl + alkyl gives Wurtz reaction, aryl + aryl gives Fittig reaction, and alkyl + aryl gives Wurtz-Fittig reaction.

Answer 1

The Correct Option is C

Step 1: Identify the reactants involved.
The question states that there is a mixture of an alkyl halide and an aryl halide reacting with sodium metal in dry ether. This combination of reactants and conditions is very important for identifying the name of the reaction. Step 2: Recall the named reactions.
When two alkyl halide molecules react with sodium in dry ether, the reaction is called the Wurtz reaction.
When two aryl halide molecules react with sodium in dry ether, the reaction is called the Fittig reaction.
When one alkyl halide and one aryl halide react together with sodium in dry ether, the reaction is called the Wurtz-Fittig reaction.
Step 3: Compare with the given options.

• (A) Fittig reaction: Incorrect. This reaction involves coupling of two aryl halides.
• (B) Finkelstein reaction: Incorrect. This is a halogen exchange reaction, usually involving alkyl chlorides or bromides with sodium iodide in acetone.
• (C) Wurtz-Fittig reaction: Correct. This reaction involves coupling between an alkyl halide and an aryl halide in the presence of sodium in dry ether.
• (D) Wurtz reaction: Incorrect. This reaction involves coupling of two alkyl halides.

Step 4: Conclusion.
Since the reaction is between an alkyl halide and an aryl halide in the presence of sodium in dry ether, the correct name of the reaction is Wurtz-Fittig reaction.
Final Answer:Wurtz-Fittig reaction.
