Kjeldahl method for estimation of nitrogen is not applicable to

Question

Kjeldahl method for estimation of nitrogen is not applicable to (A) pyridine (B) hexamethylene diamine (C) propan-1-amine (D) 2-phenylethanamine

Tardigrade Admin · Accepted Answer

Kjeldahl method can not be used for compounds having azo groups (-N = N-) nitroso (-NO) azoxy compounds <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/b4abbd30efc466f9cf33dc600dfe07ff-.png" /> and nitrogen in the ring (pyridine, quinoline etc.) Since, nitrogen in these compounds is not quantitatively converted into ammonium sulphate.

propan-1-amine

2-phenylethanamine

Kjeldahl method can not be used for compounds having azo groups $(- N = N -)$ nitroso $(- NO)$ azoxy compounds

and nitrogen in the ring (pyridine, quinoline etc.) Since, nitrogen in these compounds is not quantitatively converted into ammonium sulphate.
