QJEEM20Ch2cab: JEE Main 2020 Chemistry - Class 12 JEEM20Ch2cab Solution: The correct statement with respect to dinitrogen is :
The correct statement with respect to dinitrogen is :
Multiple Choice Options
- A N2 is paramagnetic in nature
- B it can be used as an inert diluent for reactive chemicals
- C it can combine with dioxygen at 25oC
- D liquid dinitrogen is not used in cryosurgery
Step-by-Step Verified Solution
(1) N2 is diamagnetic, with no unpaired elctrons.
(2) In iron and chemical Industry because of its inertness it is used where an inert atmosphere is required.
(3) N2 does not combine with oxygen, hydrogen or most other elements. Nitrogen will combine with oxygen, however in the presence of lightining or a spark.
(4) Liquid nitrogen is used as a refrigerant to preserve biological material food items and in cryosurgery.
