Why is `N_(2)` less reactive at room temperature ?

Text Solution

Verified by Experts

Dinitrogen `N_(2)`, has high bond enthalpy due to triple bond, `N-=N`.
(ii) Nitrogen has an electronic configuration with extra stability of half filled 2p-orbitals, `(7N=1s^(2),2s^(2),sp_(x)^(1),2p_(y)^(1),2p_(z)^(1))`.
(iii) Hence, `N_(2)` is unreactive and inert at low or room temperature.
