Ammonia on reaction with hyprochlorite ions can form

Options

A. `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

1

Explanation

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`
