For which of the following compounds Kjeldahl method can be used to determine the percentage of Nitrogen ?
- A Nitrobenzene
- B Pyridine
- C Alanine
- D Diazomethane
Answer & Solution
Correct Answer
(C) Alanine
Step-by-step Solution
Detailed explanation
Kjeldahl's method is not applicable for cpmpounds containing nitrogen in nitro and azo groups and nitrogen present in the ring. Because nitrogen of these compounds does not change to ammonium sulphate under these conditions. Hence only Alanine can be used to determine percentage…
