Given below are two statements : Statement I : In Lassaigne's test, the covalent organic molecules are transformed into ionic compounds. Statement II : The sodium fusion extract of organic compound having N and S gives prussian blue colour with FeSO4 and Na4[Fe(CN)6] In the light of the above statements, choose the correct answer from the options given below

1. Both Statement I and Statement II are true
2. Both Statement I and Statement II are false
3. Statement I is false but Statement II is true
4. Statement I is true but Statement II is false

Correct answer: Statement I is true but Statement II is false

Solution

Statement I is correct because Lassaigne's test involves fusing organic compounds with sodium, which converts covalent compounds into ionic forms for analysis. However, Statement II is incorrect as the formation of Prussian blue specifically indicates the presence of cyanide ions, which is not a direct result of the sodium fusion extract containing nitrogen and sulfur.
