Why is dinitrogen rather inert at room temperature?
Options
- ABecause of the high bond enthalpy of the N≡N bond.
- BBecause of the low solubility of dinitrogen in water.
- CBecause of the high freezing point of dinitrogen.
- DBecause of the low boiling point of dinitrogen.
Correct answer
A. Because of the high bond enthalpy of the N≡N bond.
Step-by-step solution
The paragraph states that dinitrogen is rather inert at room temperature because of the high bond enthalpy of the N≡N bond. The N≡N bond is a triple bond, which is the strongest type of chemical bond. This makes dinitrogen difficult to react with other substances at room temperature.
