Write the sort note on. 1 Wurtz reaction, 2Fitting reaction​

Answer 1

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 and 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, activatedcopper, 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.

Fittig reaction is the chemical reaction of aryl halides with alkyl halides and sodium metal in the presence of dry ether to give substituted aromatic compounds. ... The reaction works best for forming asymmetrical products if the halide reactants are somehow separate in their relative chemical reactivities.

Hope it will help you..

Answer 2

Answer:

1. wrutz reaction is a reaction of producing saturated hydro carbons alkyl halides. this reaction is done with solid sodium in the presence of dry ether. this results in the formation of saturated hydrocarbon and release of sodium halide
2. the fittig reaction is the chemical reaction of alkyl halides and sodium metal in the presence of dry ether to give substitute aromatic compounds. the reaction works best for forming asymmetrical products if the halide reactants are somehow separated in their relative chemical activities
