Chapter 8, Problem 8.83QP

Interpretation Introduction

Interpretation: In a molecule containing $\text{S}$ and $\text{O}$ atoms, if the structure with a negative formal charge on sulfur contributes more to bonding than an alternative structure with a negative formal charge on oxygen is to be stated with explanation.

Concept introduction: Any negative formal charge should be assigned on the atoms of the most electronegative element(s).

Formal charge is calculated as,

$\text{Formal}\text{charge}=\text{Valence}\text{electrons}-\left(\text{Lone}\text{pair}\text{electrons}+\frac{1}{2}\text{Bond}\text{pair}\text{electrons}\right)$

To determine: If the structure with a negative formal charge on sulfur contribute more to bonding than an alternative structure with a negative formal charge on oxygen with explanation.
