Compound A having molecular formula `C_(7)H_(7)NO_(2)` can undergo reduction with `Sn+HCl` treatement of A with `KMnO_(4)` gives a compound B `(C_(7)H_(5)NO_(4))` which has lower boiling point compared to its other isomer. B when treated with `SOCl_(2)` produces C. C when treated with `CH_(2)N_(2)` produces D of molecular formula `C_(8)H_(5)N_(3)O_(3)` D when treated with `Ag//H_(2)O` produces E.
