- C
- D
Answer & Solution
Correct Answer
(D)
Step-by-step Solution
Detailed explanation
Lassaigne's extract is used for the detection of nitrogen and sulphur. In this the organic compound reacts with the sodium thiocyanate followed by the Fe3+ cation and formed the [Fe(SCN)]2+ complex which is red blood colour. For the test of halogens, it is necessary to remove…
