Chapter 8, Problem 106AP

Interpretation Introduction

Interpretation:

The three resonance structures of ${\text{HSO}}_3{}^{-}$ ion are to be drawn and the formal charge on them areto be shown.

Concept introduction:

For many molecules, it is impossible to explain all the properties by a single Lewis structure. In such cases, more than one Lewis structures are drawn to explain the properties. Such structures of a compound are called resonating structures and this phenomenon is called resonance.

Due to attraction toward electrons, the ions and the molecules acquire some charge, which is called the formal charge.

The formal charge is given by:

Total number of valence electrons in a free atom - total number of associated electrons.
