Vedclass · Answer

(A) The Lassaigne test is used for the detection of nitrogen,sulfur,and halogens in organic compounds. Since these elements are covalently bonded in organic compounds,they cannot be detected directly by standard precipitation reactions. Therefore,the fundamental principle of the Lassaigne test is to fuse the organic compound with metallic sodium $(Na)$. This process converts the covalently bonded elements into their corresponding water-soluble ionic salts (e.g.,$NaCN$,$Na_2S$,$NaCl$),which can then be easily identified using standard chemical reagents.
