The Beilstein test is used for the detection of:

In the qualitative test for the identification of the presence of phosphorus,the compound is heated with an oxidizing agent. It is further treated with nitric acid and ammonium molybdate,respectively. The yellow-coloured precipitate obtained is:

Which of the products indicates the presence of sulphur atom in an organic compound,in qualitative elemental analysis?

Presence of halogen in organic compounds can be detected using

An organic compound $A$ is oxidized with $Na_2O_2$ followed by boiling with $HNO_3$. The resultant solution is then treated with ammonium molybdate to yield a yellow precipitate. Based on the above observation,the element present in the given compound is:

Lassaigne's test is not used for the detection of the element . . . . . . in the organic compound.
