A) \[\frac{2}{3}\text{m}/\text{s}\]
B) \[{{\lambda }_{0}},\]
C) \[\frac{25}{16}{{\lambda }_{0}}\]
D) \[\frac{27}{20}{{\lambda }_{0}}\]
Correct Answer: D
Solution :
For the detection of nitrogen Lassaigne's test is used. In this test blue colour is obtained due to\[\text{1}.\text{96}\times \text{1}{{0}^{-\text{8}}}\text{ m}/\text{s}\] \[\text{2}.\text{12}\times \text{1}{{0}^{\text{8}}}\text{ m}/\text{s}\]
