From the following list of organic compounds, identify the ones whose nitrogen content CAN be succes — Qualitative and Quantitative Analysis Chemistry Question

💡 Solution & Explanation

Kjeldahl's method works well for amines (like aniline and benzylamine) and amides (like urea). It fails for compounds containing nitro groups (nitrobenzene), azo groups, or nitrogen strictly within a stable heterocyclic aromatic ring. Therefore, nitrobenzene cannot be estimated this way.
