WebWurtz Reaction. In wourtz reaction a solution of alkyl halide in ether on heating with sodium gives alkane. An alkyl halide on Wurtz reaction leads to the formation of symmetrical alkane having an even number of carbon atoms. Two different alkyl halides, on Wurtz reaction give all possible alkanes. WebThe 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 …
