The reduction of nitrobenzene in a neutral medium (by a reducing agent like zinc in aqueous ${\mathrm{NH}}_4\mathrm{Cl}$ produces.

Pheylhydroxylamine is created when nitrobenzene is reduced with a neutral reducing agent ($\mathrm{Zn}$ dust$+{\mathrm{NH}}_4\mathrm{Cl},\mathrm{Al}-\mathrm{Hg}$ pair, and water).
