In the most stable resonance hybrid structure of the azide ion (), which of the following statements — Chemical Bonding Chemistry Question

💡 Solution & Explanation

The azide ion $[N=N=N]^-$ is linear ($sp$ hybridized). The central nitrogen forms 4 bonds with 0 non-bonding electrons, giving it a formal charge of $5 - 0 - \frac{8}{2} = +1$. The terminal nitrogens each have 2 bonds and 4 non-bonding electrons: $5 - 4 - \frac{4}{2} = -1$.
