Question

In the sodium fusion test of organic compounds, the nitrogen of an organic compound is converted to:

• A. sodium cyanide
• B. sod-amide
• C. sodium nitrite
• D. sodium nitrate

Answer 1

The correct option is A sodium cyanide

If nitrogen is present in the compound, the Lassaigne's extract would contain sodium cyanide formed during fusion. Sodium cyanide is converted to sodium ferrocyanide on treating with ferrous sulphate. On further treating it with ferric chloride, a Prussian blue complex, ferric ferrocyanide is formed.

So in Sodium fusion test of organic compounds, the nitrogen of an organic compound is converted to Sodium Cyanide
