Question

Given below are two statements:
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.

Step 1: Evaluate Statement I

"Kjeldahl method is applicable to estimate nitrogen in pyridine."

❌ FALSE — Kjeldahl's method CANNOT be used for pyridine. Pyridine is a heteroaromatic compound with nitrogen in a ring. The ring nitrogen is NOT converted to ammonium sulphate  during Kjeldahl digestion. Kjeldahl's method fails for:
- Nitro compounds ()
- Azo compounds ()
- Nitriles ()
- Pyridine and other heteroaromatic N compounds

Step 2: Evaluate Statement II

"The nitrogen present in pyridine ca
