Chapter 9, Problem 9.130QP

Interpretation Introduction

Interpretation:

The favored resonance formulas of given molecules has to be explained using formal charge.

Concept introduction:

Electronic configuration:   Electronic configuration is the arrangement of electrons that revolves around the nucleus in a specific orbits.  The electrons arranged in lower energy orbital level to higher level orbital.

Every stable molecule has eight electrons in its outer most shell and this is based on octet rule.  If Outer most shell is completely filled or half field shell or empty then they are more stable

Formal charge

$\text{FC=}\left[\text{valence electrons}\right]\text{ – }\left[\text{electrons in lone pairs + 1/2 the number of bonding electrons}\right]\text{.}$
