Question

Question 12.26 Explain the reason for the fusion of an organic compound with metallic sodium for testing nitrogen, sulphur and halogens.

Class XI Organic Chemistry : Some Basic Principles and Techniques Page 363

Answer 1

Hi

Here is your answer,

Nitrogen, sulphur and halogens are present in an organic compound in covalent form so their detection is not easy. By fusing with Na metal these elements are converted into NaCN or Na₂S or NaX, in an ionic form. In ionic form, these can be easily detected by ionic reactions.


Hope it helps you !

Answer 2

Detection of Nitrogen , sulphur and halogens isn't easy because Nitrogen , sulphur and halogens are present in an organic compound in covalent form. if we fuse with Na metal , these elements are converted into NaCN , Na2S and NaX respectively. e.g., in an ionic form . in ionic form , we can easily detect ionic reactions. That's why we have to fuse of an organic compound with Na metal for testing Nitrogen , sulphur and halogens.
