Benzoin is an organic compound with the formula PhCH(OH)C(O)Ph. It is
a hydroxy ketone attached to two phenyl groups.
To answer your question, the balanced oxidation-reduction reaction equation for the
oxidation of benzoin by ammonium nitrate is:
2Ph-C(OH)-C(O)-Ph+NH4NO3
--> 2Ph-C(O)-C(O)-Ph + N2 + 3H2O.
