Products forms when Ammonia reacts with sodium hypochlorite are:

Hydrazine is N₂H₄ and one of the well-known methods for preparing hydrazine is the Raschig process. In this process, ammonia reacts with sodium hypochlorite (NaOCl) to form hydrazine along with NaCl and water.

${2\mathrm{NH}}_3+\mathrm{NaOCl}⟶{\mathrm{N}}_2{\mathrm{H}}_4+\mathrm{NaCl}+{\mathrm{H}}_2\mathrm{O}$
