The Wurtz reaction, named after Charles-AdolpheWurtz, is a coupling reaction in organic chemistry, organometallic chemistry and recently inorganic main group polymers, whereby two alkyl halides arereacted with sodium metal in dry ethereal solution to form a higher alkane:

Since halogen atoms are more electronegative than carbon, the carbon-halogen bond of alkyl halide is polarised; the carbon atom bears a partial positive charge whereas the halogen atom bears a partial negative charge. This is responsible for nucleophilic substitution reactions, elimination reactions and reaction of alkyl hlides with a metal to form organometallic compounds.
