1.	In the Lassaigne's test for nitrogen in an organic compound, the Prussian blue colour is obtained due to the formation of : (a) Na_(4)[Fe(CN)_(6)] (b) Fe_(4)[Fe(CN)_(6)]_(3)(c) Fe_(2)[Fe(CN)_(6)] (d) Fe_(3)[Fe(CN)_(6)]_(4)
Answer» SOLUTION :The prussian blue colour is due to the formation `Fe_(4)[FE(CN)_(6)]_(3)`. Thus, OPTION (b) is correct.
