Chapter 6, Problem 6.20YT

Interpretation Introduction

Interpretation:

In the given graphic, the curved arrows that convert each resonance structure of ${\text{C}}_{\text{6}}{\text{H}}_{\text{5}}{\text{NH}}^{\text{-}}$ to the one on its right are to be shown. Also, the resonance hybrid is to be drawn for the same.

Concept introduction:

A resonance structure exists in species which have two or more valid Lewis structures. Resonance structures differ only in the placement of their valence electrons, not their atoms. Resonance structures are imaginary; the one, true species is represented by the resonance hybrid. A resonance hybrid is a weighted average of all resonance structures. The resonance hybrid looks most like the lowest energy (most stable) resonance structure. A resonance structure is lower in energy (i.e., more stable) with a greater number of atoms having an octet, with more covalent bonds, and with fewer atoms having a nonzero formal charge.
