1.	Excess of ammonia with sodium hypochlorite solution in the presense of gule or gelatin givesA. `NaBH_(2)`B. `NH_(2)NH_(2)`C. `N_(2)`D. `NH_(4)Cl`
Answer» Correct Answer - B Excess of ammonia `(NH_(3))` when reacts with sodium hypochlorite solution (NaOCl) in presence of glue or gelatin gives hydrazine `(NH_(2)*NH_(2))`. This process is known as Reschig process `2NH_(3)+NaOC l toN_(2)H_(4)+NaCl+H_(2)O` Addition of gelatin or glue suppress the side reaction by complexing with the metal ions and yield of hydrazine is increased.
