Chapter 10, Problem 47E

Interpretation Introduction

Interpretation:

The phenomenon of resonance in nitrite ion ( ${\text{NO}}_{\text{2}}{}^{\text{-}}$ ) with the help of Lewis strictures should be shown.

Concept introduction:

Resonance is a set consists of two or more than two Lewis structure of the same molecule. It shows the equivalent structure having fractional bonds and fractional charges. Two resonance structures have the same number of atoms and electrons but the arrangement of atoms can be different.

These different equivalent structures obtained after shifting of the double bond in the ring. The shifting of double bonds takes place due to the shifting of electrons in it.

A group which is linked to the aromatic ring may results either in withdrawing or releasing of electrons in the ring which produces the resonating structure by shifting the double bonds.
