Explain the reason for the fusion of an organic compound with metallic sodium for testing nitrogen, sulphur and halogens.

Solution :-

Nitrogen, sulphur, and halogens are covalently bonded in organic compounds. For their detection, they have to be first converted to ionic form. This is done by fusing the organic compound with sodium metal because sodium is very reactive. This is called “Lassaigne’s test”. The chemical equations involved in the test are

\( Na +C +N\rightarrow NaCN\)

\( Na+ S+ C+ N\rightarrow NaSCN\)

\( 2Na+ S\rightarrow Na_2 S\)

\( Na+ X\rightarrow NaX\)

(X= Cl, Br, I)

Carbon, nitrogen, sulphur, and halogen come from organic compounds.
