Lassaigne's test: Ionic bond converts to covalent bond.
Lassaigne's test: Ionic bond converts to covalent bond.
Show Hint
Remember that Lassaigne's test detects elements through their respective salts formed during the reaction with sodium metal and does not involve a transformation between ionic and covalent bonds.

- True
- False
Show Solution
The Correct Option is B
Solution and Explanation
Lassaigne's test is employed to identify nitrogen, sulfur, and halogens within organic compounds. The procedure entails heating the organic substance with sodium metal. The assertion that "an ionic bond converts to a covalent bond" during Lassaigne's test is erroneous. The reaction primarily results in the formation of sodium salts; it does not directly transform ionic bonds into covalent bonds.Consequently, the accurate response is False.
