Step 1: Understanding the Concept:
Coupling reactions using Sodium metal are named based on the types of halides being joined together. Step 2: Formula Application:
1. Wurtz Reaction: Two alkyl halides ($R-X + R-X$).
2. Fittig Reaction: Two aryl halides ($Ar-X + Ar-X$).
3. Wurtz-Fittig Reaction: One alkyl and one aryl halide ($R-X + Ar-X$). Step 3: Explanation:
The reaction involves the coupling of an alkyl group and an aryl group to form an alkyl-substituted aromatic compound (like Toluene).
$R-X + 2Na + X-Ar \xrightarrow{\text{dry ether}} R-Ar + 2NaX$. Step 4: Final Answer:
The reaction is the Wurtz-Fittig reaction.
