Vedclass · Answer

(C) The Kjeldahl method is used for the quantitative estimation of nitrogen in organic compounds. However,it is not applicable to compounds containing nitrogen in nitro groups $(-NO_2)$,azo groups $(-N=N-)$,or heterocyclic rings (like pyridine) because the nitrogen in these compounds cannot be quantitatively converted to ammonium sulfate under the conditions of the Kjeldahl method. Among the given options,$CH_3-CH_2-NH_2$ (ethylamine) is an aliphatic amine where nitrogen is not part of a ring or a nitro/azo group,so the Kjeldahl method is applicable to it.

In which of the following compounds is the Kjeldahl method applicable?
