Total number of compounds amongst the following that CANNOT be used for Kjeldahl's method for estimation of nitrogen is/are ____.
1 6
2 5
3 1
4 4
Explanation:
Kjeldahl's method cannot be used for: i. organic compounds containing nitrogen in the ring such as I and IV. ii. organic compounds containing diazo \(\left( { - {\rm{N}} = {\rm{N}} - } \right)\) and \({\mathrm{\left(-\mathrm{NO}_{2}\right)}}\) group like III and VI.

In Kjeldahl's method, ammonia from \(5 \mathrm{~g}\) of food neutralizes \(30 \mathrm{~cm}^{3}\) of \(0.1 \mathrm{~N}\) acid. The percentage of nitrogen in the food is

Kjeldahl's method cannot be used for the estimation of nitrogen in
1 pyridine
2 nitro compounds
3 azo compounds
4 All of these
Explanation:
Kjeldahl's method cannot be used for the estimation of nitro and azo compounds and other compounds containing nitrogen in the ring (like pyridine) because these compounds are not converted into \(\left(\mathrm{NH}_{4}\right)_{2} \mathrm{SO}_{4}\) during. reaction.
