Here paragraphs are given. Based upon the paragraphs some multiple choice questions are given. Each question has 4 choices A, B, C and D. Out of which one is correct. Choose the correct option Paragraph/comprehension In the detection of elements by Lassaigne’s test, the covalent compounds are converted into ionic compounds on fusion with sodium metal. The nitrogen, sulphur and halides present in the organic compounds are test with their usual tests. In this test blue or green colour is obtained when only nitrogen is present whereas red colour is obtained when both nitrogen and sulphur are present. The Lassaigne’s extract is boiled with HNO_(3) so as to decompose Na_(2) and NaCN if present. Phosphorus is detected in the organic compound by fusing it with sodium peroxide. When sodium phosphate formed is detected with cone. HNO_(3) and ammonium molybdate. The Lassaigne's extract is boild with dil. HNO_(3) before testing for halogens because

Lassaigne's extract is botted with dilute HNO_(3) before testing for halogens because :

Lassaigne’s extract is heated with cone. HNO_(3) before testing for halogens because
