Question

Given below are two statements: 
Statement (I): Nitrogen, sulphur, halogen, and phosphorus present in an organic compound are detected by Lassaigne's Test.
Statement (II): The elements present in the compound are converted from covalent form into ionic form by fusing the compound with Magnesium in Lassaigne's test. 
In the light of the above statements, choose the correct answer from the options given below:

• A. Both Statement I and Statement II are false
• B. Both Statement I and Statement II are true
• C. Statement I is false but Statement II is true
• D. Statement I is true but Statement II is false

Hint:

In Lassaigne's Test, the organic compound is fused with sodium metal to detect the presence of elements like nitrogen, sulfur, halogens, and phosphorus by converting them into ionic forms for easy detection.

Answer 1

The Correct Option is B

Step 1: Statement (I) is correct. Lassaigne's test is used to detect the presence of nitrogen, sulfur, halogens, and phosphorus in an organic compound by fusing it with sodium metal to form sodium salts of these elements. 

Step 2: Statement (II) is also correct. In Lassaigne's test, the elements are converted into their ionic forms by fusing the organic compound with sodium or magnesium. This makes it easier to test for the presence of elements like nitrogen, sulfur, and halogens. 

Thus, the correct answer is that both Statement I and Statement II are true.
