Question

. In ion N3
-
individual nitrogen atoms oxidation state 1) -2, -1, +3 2) -1, +1, -1 3) +1, +1, -3 4) -3, -3, -3

Answer 1

To find:

Oxidation State of all Nitrogen atoms present in the azide ion.

Calculation:

Structure of Azide ion is represented in resonance form, such that there is equilibrium amongst the canonical forms.

Refer to the attached diagram to understand the resonance in the ion.

Now , let's consider the 2nd structure:

The extreme left and right nitrogen has -1 charge and hence is in -1 oxidation state.

And due to excessive electron donation by central Nitrogen atom , its oxidation state is +1.

So, correct option is ,

$\boxed{ \bf{ oxidation \: state : \: - 1, + 1, - 1}}$
