The Correct Option is A
Solution and Explanation
Step 1: Understanding the Question:
We need to identify the Wurtz-Fittig reaction among the given options.
Step 2: Key Formula or Approach:
Wurtz-Fittig reaction is a coupling between an aryl halide and an alkyl halide using sodium metal in dry ether to form an alkylarene.
Step 3: Detailed Explanation:
- (A): Aryl halide (C\(_6\)H\(_5\)Cl) + alkyl halide (CH\(_3\)Cl) → toluene – Wurtz-Fittig. - (B): Two alkyl halides → alkane – simple Wurtz reaction. - (C): Same alkyl halide – simple Wurtz. - (D): Two aryl halides – Fittig reaction.
Thus, only (A) is Wurtz-Fittig.
Step 4: Final Answer:
Option (A) is correct.
