JEE Main 2024 — 8 April, Shift 2 — Question 74
Given below are two statements, one is labelled as Statement I and the other is labelled as Statement II.
Statement (I) : Kjeldahl method is applicable to estimate nitrogen in pyridine.
Statement (II) : The nitrogen present in pyridine can easily be converted into ammonium sulphate in Kjeldahl method.
In the light of the above statements, choose the correct answer from the options given below:
- Option A:Correct
Both Statement I and Statement II is false
- Option B:
Statement I is false but Statement II is true
- Option C:
Both Statement I and Statement II is true
- Option D:
Statement I is true but Statement II is false
Answer: A
Step-by-step solution
Statement I is False: The Kjeldahl method is not applicable for the estimation of nitrogen present in heterocyclic compounds such as pyridine. Hence, nitrogen in pyridine cannot be estimated by this method.
Statement II is False: In pyridine, nitrogen is part of the aromatic ring system and does not get converted into ammonium sulphate during reaction with concentrated in the Kjeldahl method. Therefore, the nitrogen present in pyridine is not easily converted into .
Thus, Both Statement I and Statement II is false.
