In the detection of nitrogen of an organic compound by Lassaigne's test, a prussian blue colour is obtained. This is due to the formation of which of the following complexes?
- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
Detection of nitrogen is done with the help of Lassaigne's extract. It is boiled with iron sulphate and then acidified with concentrated with sulphuric acid. The appearance of a prussian blue colour confirms the presence of nitrogen.…
