Chemistry · Qualitative analysis: Detection of nitrogen, sulphur, phosphorus and halogens
The presence of nitrogen in the organic compound is tested as:
The presence of nitrogen in the organic compound is tested as:
- A. \( N_{2} \)
- B. \( N H_{3} \)
- C. \( N O \)
- D. \( C N \)
Step-by-step solution
In Lassaigne's test, nitrogen in organic compounds is converted to sodium cyanide (NaCN) when fused with sodium. The cyanide ion (CN) is then detected via formation of Prussian blue with FeSO4 and FeCl3.
