Answer: The only energy difference between the staggered and eclipsed forms of ethane is 12.55 kJ/mol. The more reactive alkyl halide forms an organo sodium first, and this reacts as a nucleophile with an aryl halide. Answer: In Wurtz Reaction, two alkyl halides (preferably the same) react with the Na metal in the presence of dry ether to form a symmetrical alkane having even number of C-atoms. When the aryl halide is reacted with sodium metal, an intermediate organo-alkali compound is formed, which is followed by a nucleophilic attack of the alkyl halide as shown below. Wurtz reaction usually undergoes rearrangement and elimination, so in order to avoid it, organotin can be used in place of organolithium. There are 28 basic reactions in organic chemistry class 12th.
