1.	How will you detect nitrogen from organic compounds?
Answer» Solution :Detection of Nitrogen: The following REACTIONS are involved in the detection of nitrogen with formation of prussian blue precipitate conforming the presence of nitrogen in an organic compound. (i) `UNDERSET("Sodium")(Na)+underset("From organic compound")(C+N) to underset("Sodium cyanide")(NACN)` (ii) `underset("Ferrous SULPHATE")(FeSO_(4))+underset("Sodium hydroxide")(2NaOH)to underset("Ferrous hydroxide")(Fe(OH)_(2))+Na_(2)SO_(4)` (iii) `6NaCN+Fe(OH)_(2) to underset("sodium ferrocyanide")(Na_(4)[Fe(CN)_(6)]+2NaOH` (iv) `3Na_(4)[Fe(CN)_(6)]+4FeCl_(3)to underset("Ferric ferrocyanide "("Prussian blue precipitate"))(Fe_(4)[Fe(CN)_(6)]darr+12NaCl`
