Question

Which reagents are required for one step conversion of Chlorobenzene to Diphenyl?

• A. Chlorobenzene, Na, Dry ether \hspace{0.5cm}
• B. Benzene, Anhydrous AlCl\(_3\)
• C. Chlorobenzene/Fe, Dark \hspace{1.3cm}
• D. NaNO\(_2\) + HCl

Hint:

The Wurtz-Fittig reaction is useful for forming biaryl compounds like diphenyl by coupling halides with sodium metal.

Answer 1

The Correct Option is A

Chlorobenzene can be converted to diphenyl through reaction with sodium in dry ether. This process, termed the Wurtz-Fittig reaction, involves sodium electron donation to chlorobenzene, yielding biphenyl.
