Question

Detect the presence of nitogen atom in a given organic compound o

Answer 1

Test for Nitrogen in Organic compound:

Step 1: Sodium metal is fused with organic compound containing Nitrogen and Crabon.it Gives Sodium cyanide which is soluble in water.

 Na+ N+ C ----> NaCN.

Step 2:Sodium Cyanide is converted into Sodium ferrocynaide by adding ferrous sulphate.

6NaCN+FeSO4 ----> Na₄ [Fe(CN)₆] + Na₂SO₄

Step 3:

Ferric ions formed during this process react with ferrocynaide to form blue precipitate of Ferric ferrocyanide.

 Na₄ [Fe(CN)₆]  +Fe³⁺  ----> Fe₄[Fe(CN)₆]₃
