1.	Ammonia on reaction with hyprochlorite ions can formA. `N_(2)H_(4)` and `NH_(4)Cl`B. `HNO_(3)` and `NH_(4)Cl`C. `N_(2)` and `N_(2)H_(4)`D. `NO` and `N_(2)H_(4)`
Answer» Correct Answer - 1 Hypochlorite ion oxidise `NH_(3)` to nitrogen `2NH_(3)+3NaClOrarrN_(2)+3NACl+H_(2)O` When the large excess of aqueous ammonia is treated with sodium hypochlorite in presence of glue or gelatine ,it gets oxidized to hydrazine (Raschig Process): `2NH_(3)+NaOClrarrunderset("Hydrazine")(NH_(2).NH_(2))+NaCl+H_(2)O` according the reaction processes in two steps ` NH_(3)+NaOCl overset("fast")rarrunderset("Chloramine")(NH_(2)Cl)+NaOH` `2NH_(3)+underset("Chloramine")(NH_(2)Cl)overset("slow")rarrNH_(2)NH_(2)+NH_(4)Cl` Glue or gelatine catalyses the slow reaction and prevents the oxidation of hydrazine to nitrogen ` N_(2)H_(4)+2NH_(2)ClrarrN_(2)+2NH_(4)Cl`
