MCQ
Which of the following compounds is not expected to show Lassaignes' test for nitrogen ?
- APropanenitrile
- ✓Hydroxylamine hydrochloride
- CNitromethane
- DEthanamine
✓
Answer
Correct option: B.
Hydroxylamine hydrochloride
b
Lassaigne's test is used for the detection of nitrogen and given by all nitrogenous compound except diazo $\rlap{-} (\,\,N = N\rlap{-} )$ compounds.
This test is shown only by the compounds containing $C$ and $N$ both hence hydroxyl amine hydrochloride $(H_2NOH .HCl)$ will not perform this test
