Answer 1

The correct option is D sodium cyanide

Nitrogenn, Sulphur, and halogens present in organic compounds are detected by Lassaigne’s test. Here, a small piece of Na metal is heated in a fusion tube with the organic compound. The principle is that, in doing so, Na converts all the elements present into ionic form.

When a nitrogenous organic compound is fused with sodium, the nitrogen present in the compound is converted into sodium cyanide.
