Describe Wurtz reaction with a
suitable example.
Answers
Wurtz Reaction :-
The wurtz Reaction, named after Charles 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 either 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.
Example :-
It is intolerant range of functional groups. wurtz coupling is however, useful in closing small , especially three membered rings. Bicyclobutane was prepared this way from 1-bromo-3-chlorocycbutane in 95% yeild.at which temperature sodium is liquid. This reaction has poor yield which is consequence of multiple product formation. In the case of (1,3),(1,4),(1,5),(1,6) dihalides.
Equation :-
The general form of wurtz Reaction equation can be written as follows :-
2R - X + 2Na → R - R + 2Na + X-
