Sometimes, the color observed in Lassaigne’s test for nitrogen is green. It is because of:
- a)Green color of ferrous sulfate
- b)Ferric ferrocyanide is also green
- c)Green color of copper sulfate
- d)Due to incomplete fusion Excess of Fe3+ ions whose yellow color makes the blue color of ferric ferrocyanide to appear green.
Correct answer is option 'D'. Can you explain this answer?

Reagent tests can vary depending on the specific compound being tested. Lassaigne reagent is a mixture of sodium metal and carbon, which is used to test for the presence of nitrogen, sulfur, and halogens in organic compounds. When the reagent reacts with a compound containing one of these elements, a colored product is formed, indicating the presence of the element.
For example, when Lassaigne reagent reacts with a compound containing nitrogen, a deep blue color is observed due to the formation of sodium ferrocyanide. This color change is often used to confirm the presence of nitrogen in organic compounds.
Similarly, when Lassaigne reagent reacts with a compound containing sulfur, a brown color is observed due to the formation of sodium sulfide. This color change is used to confirm the presence of sulfur in organic compounds.
The color observed in Lassaigne reagent tests for halogens can vary depending on the specific halogen present. For example, when Lassaigne reagent reacts with a compound containing chlorine, a yellow color is observed due to the formation of sodium chloride. On the other hand, when reacting with a compound containing bromine, a reddish-brown color is observed due to the formation of sodium bromide.
It is important to note that the color observed in Lassaigne reagent tests should be interpreted in conjunction with other tests and techniques to confirm the presence of a specific element in an organic compound.
