Interpretation Introduction

Interpretation: The Lewis structure of dimethyl sulfide $\left({\text{CH}}_{\text{3}}{\text{SCH}}_{\text{3}}\right)$, hydrogen sulphide $\left({\text{H}}_{\text{2}}\text{S}\right)$, sulphite $\left({\text{SO}}_{\text{3}}{}^{2-}\right)$ and sulphate ${\text{SO}}_{\text{4}}{}^{2-}$ ions and the species that uses expanded valence shells in any of the species is to be identified.

Concept introduction: The Lewis symbols of the atoms indicate the total number of valence electrons surrounding the atom or the ions.

To determine: The Lewis structure of dimethyl sulfide $\left({\text{CH}}_{\text{3}}{\text{SCH}}_{\text{3}}\right)$, hydrogen sulphide $\left({\text{H}}_{\text{2}}\text{S}\right)$, sulphite $\left({\text{SO}}_{\text{3}}{}^{2-}\right)$ and sulphate $\left({\text{SO}}_{\text{4}}{}^{2-}\right)$ ions and the species that uses expanded valence shells in any of the species.
