HIya PEOPLE IM STUCK ON THIS QUESTION:

in an experiment designed to test the existence of benzyne as an intermediate in nucleophilic aromatic substitution, chlorobenzene was treated with solamide (NaNH2) in liquid ammonia. the chlorobenzene was labelled with carbon-14 in the C-CL position.

a) if the reaction proceeds in accordance with the benzyne mechanism, what would be the distribution on carbon-14 in the product aniline- that is, at what positions and in what percentages would carbon-14 be found?

b) what would be the distribution of carbon-14 if the reaction proceeds by simple nucleophilic displacement?

Draw the benzyne mechanism out with the C of the C-Cl bond labelled 13C.  The answer to a) and b) should be apparent to you afterwards.

Or you could try using google to search for this information.  By searching for benzyne intermediate, in 10 seconds i was on a page that describes everything you need
