Question

Nitrogen `(N_(2))` is relatively unreactive, because
A. its electronegativity is high
B. its dissociation energy is large
C. its atomic radius is small
D. it is the first element of group

Answer 1

Correct Answer - B
Nitrogen forms strong `N-=N` triple bond. Since dissociation energy of `N-=N` tirple bond is very high, therefore, it exists as a relatively unreactive diatomic molecule in its elemental state.
