Current Question (ID: 10978)

Question:

$\text{Metallic sodium is fused with organic compounds for testing nitrogen, sulphur, and halogens. The correct reason behind this is:}$

Options:

1. $\text{To convert all compounds to their ionic form.}$ (Correct)
2. $\text{Sodium reduces the compounds.}$
3. $\text{Sodium converts all compounds in their covalent form.}$
4. $\text{None of the above.}$

Solution:

$\text{Step 1:}$ $\text{The elements such as halogens, nitrogen, and sulphur are covalently bonded to the organic compounds. For their detection, we need to convert them to their ionic form for performing respective tests for their detection.}$ $\text{As per principle, on fusion Na converts all elements present in an organic compound in ionic form. The ionic salts formed are extracted by boiling with distilled water and the process is known as sodium fusion extraction.}$ $\text{Step 2:}$ $\text{The reaction is as follows:}$ $\text{Na+C+N} \rightarrow \text{NaCN}$ $\text{2Na + S} \rightarrow \text{Na}_2\text{S}$ $\text{Na + X} \rightarrow \text{NaX(X = Cl, Br, or I)}$
