(A) Lassaigne's test is primarily used for the detection of nitrogen,sulphur,and halogens in organic compounds. In this test,the organic compound is fused with metallic sodium to convert the elements into their corresponding water-soluble sodium salts: $Na + C + N \rightarrow NaCN$ $2Na + S \rightarrow Na_2S$ $Na + X \rightarrow NaX$ (where $X = Cl, Br, I$) Boron is not detected by Lassaigne's test because it does not form a stable ionic salt under these conditions that can be easily identified by standard qualitative reagents.
