Question

The correct statement with respect to dinitrogen is:

• A. liquid dinitrogen is not used in cryosurgery.
• B. it can be used as an inert diluent for reactive chemicals.
• C. it can combine with dioxygen at $25^{\circ }C$
• D. $N_2$ is paramagnetic in nature.

Answer 1

Answer: (B)

1. Liquid nitrogen is used in cryosurgery.

2. Dinitrogen can be used as an inert diluent for reactive chemicals because due to high bond energy $(N\equiv N),$ it is very less reactive in nature.

3. At $25^{\circ }C$ (room temperature), dinitrogen does not react with dioxygen.

4. $N_2$ is diamagnetic in nature due to absence of unparied $e^{-}$ in its $M.O$. configuration.
