AP Chemistry
2.7 VSEPR and Hybridization
2.5 Lewis Diagrams
An aqueous solution of iodine is prepared by dissolving solid \(\text{I}_2\) in an aqueous solution containing iodide ions, \(\text{I}^-\), producing the triiodide complex ion according to the following equation:
\[ \text{I}_2\text{(aq)} + \text{I}^-\text{(aq)} \rightarrow \text{I}_3^-\text{(aq)} \]
Based on VSEPR theory and the distribution of valence electrons in the Lewis diagram of \(\text{I}_3^-\), which of the following correctly predicts and explains the molecular geometry of the \(\text{I}_3^-\cos\) ion?
\[ \text{I}_2\text{(aq)} + \text{I}^-\text{(aq)} \rightarrow \text{I}_3^-\text{(aq)} \]
