Question

The above reaction is an example of 

• A. Sandmeyer’s reaction
• B. Wurtz reaction
• C. Wurtz Fittig reaction
• D. Kolbe reaction

Hint:

The Wurtz Fittig reaction involves the coupling of alkyl and aryl halides to form biaryl compounds. This is similar to the Wurtz reaction, but with an aryl halide.

Answer 1

The Correct Option is C

The reaction involves the coupling of chlorobenzene (C\(_6\)H\(_5\)Cl) with sodium (Na) in dry ether, yielding biphenyl (C\(_6\)H\(_5\)-C\(_6\)H\(_5\)).
Step 1: Wurtz Fittig reaction description.
The Wurtz Fittig reaction couples an alkyl halide with an aryl halide using sodium metal in dry ether, producing biphenyl or related compounds. It is a modification of the Wurtz reaction (coupling of two alkyl halides), with the Fittig variation involving one aryl and one alkyl halide.
Step 2: Evaluation of options.
- Option 1: Sandmeyer’s reaction: Synthesizes aryl halides from diazonium salts; not for alkyl-aryl halide coupling.
- Option 2: Wurtz reaction: Couples two alkyl halides; not an alkyl-aryl coupling.
- Option 3: Wurtz Fittig reaction: Correct. Couples an alkyl halide with an aryl halide to form biphenyl.
- Option 4: Kolbe reaction: Forms carboxylates from alkyl or aryl halides with sodium; unrelated to this reaction.

Step 3: Conclusion.
This is an example of the Wurtz Fittig reaction, where an alkyl halide and an aryl halide react with sodium to form a biphenyl compound.

Final Answer: \[\boxed{\text{The correct answer is Wurtz Fittig reaction.}}\]
