JEE Mains · Chemistry · STD 11 - 8.3. Organic chemistry purification and characterization
\(0.8\, \mathrm{~g}\) of an organic compound was analysed by Kjeldahl's method for the estimation of nitrogen. If the percentage of nitrogen in the compound was found to be \(42\, \%\), then \(....\,\mathrm{mL}\) of \(1\, \mathrm{M}\) \(\mathrm{H}_{2} \mathrm{SO}_{4}\) would have been neutralized by the ammonia evolved during the analysis.
- A \(8\)
- B \(9\)
- C \(41\)
- D \(12\)
Answer & Solution
Correct Answer
(D) \(12\)
Step-by-step Solution
Detailed explanation
Organic compound : \(0.8 \,\mathrm{gm}\) wt. of \(\mathrm{N}=\left(\frac{42}{100} \times 0.8\right)\, \mathrm{gm}\) mole of \(N=\frac{42 \times 0.8}{100 \times 14}=\frac{2.4}{100}\, \mathrm{~mol}\) moles of \(\mathrm{NH}_{3}=\frac{2.4}{100}\)…
