The statement true for `N_(3)^(-)` is

Options

A. It has a non-linear structure
B. It is called pseudo halogens
C. The formal oxidation state of `N` in this anion is-1
D. It is isoelectronic with `NO_(2)`

Answer

C

Explanation

Azide ion is linear It is called a pseudo halide ion The formal charge of `N` in `N_(3)^(Theta)` is-1 because in any of the resonating structures the net charge on the ion is -1
