Quick comprehension check
“Given the molecule sulfur tetrafluoride (SF₄), identify its electron domain geometry and molecular geometry. Explain how the presence of one lone pair of electrons on sulfur influences its shape. For the molecule phosphorus trichloride (PCl₃), determine its hybridization and molecular geometry. Discuss how the lone pair of electrons on phosphorus affects its polarity.”
