Chapter 9, Problem 92CP

Interpretation Introduction

Interpretation:

The given molecules ${\text{CS and S}}_{\text{2}}$ is very unstable compared to other two given molecules namely ${\text{CO and O}}_{\text{2}}$ hence using the phi bond forming ability of $\text{O and S}$ the reason for their stability should be explained.

Concept Introduction:

Hybridization: The mixing of atomic orbitals gives the equal number of molecular orbitals.

Lewis structures: Diagrams that tell the bonding between atoms in a molecule and the lone pairs of electrons in the molecule.

Add dots for anions and remove dots for cations.  The total number of dots indicates the valence electron of an atom.

VSEPR: Valence shell electron pair repulsion theory is method to predict the geometry of the molecule from the number of electron pairs surrounding the central atom. Idea is that repulsion between electron pairs occurs and increases the separation between the terminal groups or atoms.

To Explain: The stability of ${\text{CS and S}}_{\text{2}}$ molecules using phi bond forming ability of $\text{O and S}$.
