Text Solution

AI Generated Solution

**Step-by-Step Solution:** 1. **Understanding Lassaigne's Test**: Lassaigne's test is a qualitative analysis method used to detect the presence of certain elements (like nitrogen and sulfur) in organic compounds. The test involves fusing the organic compound with sodium metal. 2. **Fusion Process**: When the organic compound containing nitrogen (N) and sulfur (S) is heated with sodium, both elements react with sodium. 3. **Formation of Products**: - If only nitrogen is present, it forms sodium cyanide (NaCN). ...
