Why we use the presence of dry ether in wurtz reaction or what is role of dry ether in wurtz reaction

							
ITS ROLE IS AS ACATYLIST
						

							
Wurtz reaction is carried out with sodium metal  which is highly reactive, hence, we have to select a solvent which will  not react with the sodium metal. Thus ether becomes the best choice.  Similarly the alkyl halide should also dissolve in the solvent . The  sodium halide formed should be insolulbe in the solvent which can be  easily removed, and alkane formed should remain in solution,   
it requires an aprotic solvent as the medium of the reaction.Dry ether proves to be a very good non-polar, aprotic solvent for this purpose.HENCE DRY ETHER IS USED.
eg. CH3I ----------> CH3 - CH3  (in presence of Sodium and Dry ether)
Please approve !
						

							Wurtz reaction of ethyl bromide with sodium metal in dry ether(reaction of haloalkane)Ch3ch2br + 2Na + br2hc-ch3~~~~~>ch3ch2ch2ch3 + 2NaBr
						

							Because Na reacts with less hindered carbon as a nucleophile. And also dry ether is a very good poly-aprotic solvent. Hence, it is a suitable catalyst for this reaction.
						

							Dry ether is used to absorb moisture content  because metals are highly reactive with water which can form oxide and hydroxides and disturb the reaction .
						

							
when methyl bromide react with a sodium metals in presence of dry ether it gives higher ehane and sodium bromide this reaction follow the mechanism of nucliophilic substitution reaction
