Q.
The statement true for azide ion$(N_{3}^{{\ominus}})$is
Chemical Bonding and Molecular Structure
Solution:
A zide ion is linear. It is called a pseudo halide ion. The formal charge of $N$ in $N_{3}^{\ominus}$ is $-1$ because in any of the resonating structures, the net charge on the ion is $- 1$.
