The statement true for azide ion (\[{{N}_{3}}^{\odot }\]) is

A)  It has a non-linear structure

B)  It is called pseudo halogens

C)  The formal oxidation state of N in this anion I -1

D)  It is isoelectronic with \[N{{O}_{2}}\]

Correct Answer: C

Solution :

[c] Azide ion is liner. It is called a pseudo halide ion. The formal charge of N in \[{{N}^{\odot }}_{3}\]is -1 because in any of the resonating structures, the net charge on the ion is-1.
