hi guys i found this question do you know the answer of it and how to solve it?

Compound A, C8H10, undergoes nitration to give 2 products. The 1H NMR spectrum of A shows a complex four-proton multiplet at 7.04-7.43 δ and a six-proton singlet at 2.34 δ. What is the structure of A?

    'Dr Bob' is missing an isomer here...m-xylene (1,3-dimethylbenzene) could give three mono-nitrated products - -NO2 ortho to both methyls; -NO2 ortho to one methyl and para to the other; and, as a very minor (but still possible) product, meta to both methyls.

    o-xylene (1,2-dimethylbenzene) only gives two products on mononitration; p-xylene only gives one mono-nitration product.

    So your answer must be 1,2-dimethylbenzene.

    It must be m-Xylene.
