MCQ
Dumas method involves the determination of nitrogen content in the organic compound in the form of
- A$NH_3$
- ✓$N_2$
- C$NaCN$
- D$(NH_4)_2SO_4$
✓
Answer
Correct option: B.
$N_2$
b
Dumas' method involves the determination of nitrogen content in the organic compound in the form of nitrogen $\left( N _2\right)$. Organic compound is oxidized with cupric oxide in an atmosphere of carbon dioxide which gives free nitrogen along-with carbon dioxide and water.
