Vedclass · Answer

(A) In Lassaigne's test,the organic compound is fused with metallic sodium. When nitrogen $(N)$ is present,it reacts with sodium and carbon to form sodium cyanide: $Na + C + N \xrightarrow{\Delta} NaCN$. When sulphur $(S)$ is present,it reacts with sodium to form sodium sulphide: $2Na + S \xrightarrow{\Delta} Na_2S$. If both nitrogen and sulphur are present together,they form sodium thiocyanate: $Na + C + N + S \xrightarrow{\Delta} NaSCN$.

During Lassaigne's test,if $N$ and $S$ are present individually in an organic compound,they are converted into:
