Question Description
Passage IIWhen compound 1 is heated with C2H5ONa compound 2 and 3 are formed:Two mechanisms were proposed for reaction I.Mechanism A HBr is eliminated from compound 1 to form a symmetrical vinyl carbene intermediate A, which then rearranges to compound 2.Mechanism B Ethoxide ion first abstract a proton to form a carbanion intermediate B which then rearranges with loss of bromide ion to form compound 2To distinguish between the two machanisms, an isotopic labeling experiment was designed. Two compounds (Compound 4 and 5) were labelled with C-14 and each was treated separately with sodium ethoxide under identical experimental condition where following results were obtained.Q.Based on the results of scheme 1, the chemist most likely ruled out mechanism A because they assumed that intermediate A should have formeda)compound 6 onlyb)compound 7 onlyc)equal amounts of 6 and 7d)neither compound 6 nor 7Correct answer is option 'C'.
