Why is dinitrogen rather inert at room temperature?

Options

  1. ABecause of the high bond enthalpy of the N≡N bond.
  2. BBecause of the low solubility of dinitrogen in water.
  3. CBecause of the high freezing point of dinitrogen.
  4. 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.
