Chapter 7, Problem 81AE

Interpretation Introduction

Interpretation: The Lewis structures and the molecular structure of ${\text{SF}}_{\text{4}}$ and ${\text{SF}}_5{}^{-}$ are to be determined.

Concept introduction: The Lewis structure represents all bonding and non-bonding electrons surrounding the atoms involved in a molecule. A molecule exhibits a particular molecular structure in space considering the steric hindrances of the bond pairs and lone pairs of electron.

The molecular geometry of the compound containing five groups around it is trigonal bipyramidal and the molecular structure for the compound having four bonds and one lone pair of electrons is seesaw.
The molecular geometry of the compound containing six groups around it is octahedral and the molecular structure for the compound having five bonds and one lone pair of electrons is square pyramidal.

To determine: The Lewis structure and the molecular structure of ${\text{SF}}_{\text{4}}$ and ${\text{SF}}_5{}^{-}$ .
