Explanation:
The Wurtz reaction, named after Charles Adolphe Wurtz, is a coupling reaction in organic chemistry, organometallic chemistry and recently inorganic main-group polymers, whereby two alkyl halides are reacted with sodium metal in dry ether solution to form a higher alkane. In this reaction alkyl halides are treated with sodium metal in dry ethereal (free from moisture) solution to produce higher alkanes. It is also used for the preparation of higher alkanes containing even number of carbon atoms:

Other metals have also been used to effect the Wurtz coupling, among them silver, zinc, iron, activated copper, indium and a mixture of manganese and copper chloride.[1] The related reaction dealing with aryl halides is called the Wurtz–Fittig reaction. This can be explained by the formation of free radical intermediate and its subsequent disproportionation to give alkene. The Wurtz reaction occurs through a free-radical mechanism that makes possible side reactions producing alkene products.
