Question

The compound formed upon subjecting an aliphatic amine to Lassaigne&rsquo;s test isa)NaNH2b)NaNO2c)NaCNd)NaN3Correct answer is option 'C'. Can you explain this answer?

Answer

The compound formed upon subjecting an aliphatic amine to Lassaigne's test is a sodium salt of the corresponding amine.

Lassaigne's test is a chemical test used to detect the presence of nitrogen in organic compounds. In this test, the organic compound is heated with sodium metal in the presence of carbon. The nitrogen present in the compound is converted to sodium cyanide (NaCN) or sodium thiocyanate (NaSCN), depending on the presence of carbon or sulfur in the compound, respectively.

When an aliphatic amine is subjected to Lassaigne's test, the nitrogen in the amine reacts with sodium metal to form a sodium salt. For example, if the aliphatic amine is ethylamine (CH3CH2NH2), the compound formed would be sodium ethylamine (NaCH3CH2NH2).

Overall, Lassaigne's test helps in the detection and characterization of nitrogen-containing functional groups in organic compounds.
