Diphenyl can be prepared by treating two molecules of aryl halide with two molecules of sodium in presence of dry ether. The reaction is called Wurtz-fittig reaction.
i.e. $2\text{C}_6\text{H}_5\text{X}+2\text{Na}\cdots\text{dry ether}\xrightarrow{ \ \ \ \ \ \ \ \ }\text{C}_6\text{H} _5-\text{C}_6\text{H}_5+2\text{Na}\text{X}$
i.e. $2\text{C}_6\text{H}_5\text{X}+2\text{Na}\cdots\text{dry ether}\xrightarrow{ \ \ \ \ \ \ \ \ }\text{C}_6\text{H} _5-\text{C}_6\text{H}_5+2\text{Na}\text{X}$
