Hydroxylamine hydrochloride

Vedclass · Answer

(B) Lassaigne's test is used for the detection of nitrogen in organic compounds. This test involves the fusion of the organic compound with metallic sodium to convert nitrogen into sodium cyanide $(NaCN)$. Therefore,the compound must contain both carbon $(C)$ and nitrogen $(N)$ atoms to form $NaCN$. Hydroxylamine hydrochloride $(H_2NOH \cdot HCl)$ contains nitrogen but lacks carbon,so it cannot form $NaCN$ and will not show a positive result for Lassaigne's test.

Which of the following compounds is not expected to show Lassaigne's test for nitrogen?
