JEE Mains · Chemistry · STD 11 - 8.3. Organic chemistry purification and characterization
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 an organic compound having N and S gives prussian blue colour with \(\mathrm{FeSO}_4\) and \(\mathrm{Na}_4\left[\mathrm{Fe}(\mathrm{CN})_6\right]\)
In the light of the above statements, choose the correct answer from the options given below.
- A Statement I is true but Statement II is false
- B Both Statement I and Statement II are false
- C Both Statement I and Statement II are true
- D Statement I is false but Statement II is true
Answer & Solution
Correct Answer
(A) Statement I is true but Statement II is false
Step-by-step Solution
Detailed explanation
Lassaigne's test is a general test for detection of halogen, nitrogen and sulphur in an organic compound. These elements covalently bonded to the organic compounds, In order to detect them, these have to converted into ionic forms.
