While Wurtz Fittig reactions involve an alkyl halide and an aryl halide that react with the Na-metal in the presence of dry ether to form substituted aromatic compounds. 34. The production of organosilicon is done using this particular reaction although it is quite a big challenge to overcome the production in a larger quantity. In this reaction, sodium metal reacts separately with two types of halide to form aryl sodium and alkyl sodium. Although the polymer has a good heat resistance, with decomposition temperatures of the order of 400C, the polymer ( Figure 21.1) is brittle, insoluble and infusible. Even then, this reaction is used in labs for the coupling of various aromatic rings in complex organic compounds. Answer: The only energy difference between the staggered and eclipsed forms of ethane is 12.55 kJ/mol. This reaction takes place in an equilibrium process by taking the advantage of poor acetone solubility in metal halide salt that is newly formed.
