Question

In a room temperature, N₂ is less reactive. Explain why?

Answer 1

${\mathrm{N}}_2$is less reactive:-

1. The bond formed in the two nitrogen atoms in ${\mathrm{N}}_2$ is triple bond, $\mathrm{N}\equiv \mathrm{N}$.
2. It is formed by the sharing of three electron atoms between the two Nitrogen atoms.
3. Each atom has a lone pair.
4. Because of the triple bond present between the two nitrogen atoms, the bond dissociation energy is very high.
5. Bond dissociation energy is the amount of energy that is required to break a chemical bond and produce two separated atoms in an endothermic process.
6. It requires a lot of energy to break those bonds and take part in the reaction.
7. So, nitrogen is commonly referred to as an inert gas.

Therefore, In a room temperature, N₂ is less reactive.
