Lassaigne's test for the detection of nitrogen fails in
- A \(\text{NH}_2\text{CONH}_2\)
- B \(\text{NH}_2\text{- NH}_2\text{HCl}\)
- C \(\text{NH}_2\text{CONHNH}_2\text{HCl}\)
- D \(\text{C}_6\text{H}_5\text{NHNH}_2\text{HCl}\)
Answer & Solution
Correct Answer
(B) \(\text{NH}_2\text{- NH}_2\text{HCl}\)
Step-by-step Solution
Detailed explanation
Lassaigne's test for the detection of nitrogen involves the fusion of the organic compound with sodium metal to form sodium cyanide (\(\text{NaCN}\)). For the formation of cyanide ion (\(\text{CN}^{-}\)), both carbon and nitrogen must be present in the organic compound.…
