The reaction of aryl halide with sodium metal in dry ether to give biphenyl is known as

Step-by-step solution

The reaction of aryl halides with sodium metal in dry ether to form biphenyl constitutes the Fittig reaction . This transformation produces biaryl compounds through the general reaction Ar-X + 2Na + X-Ar Ar-Ar + 2NaX . The Swartz reaction employs metallic fluorides to synthesize alkyl fluorides and does not involve aryl halides or biphenyl formation. The Wurtz reaction couples two alkyl halides to form alkanes: R-X + 2Na + X-R R-R + 2NaX . Although the Wurtz-Fittig reaction involves aryl halides, it requires an alk
