Consider the chemical species IF5 + IF4+.
a. Draw the Lewis Structure and make a rough three-dimensional sketch of each species.
b. Identify the orbital hybridization, the electron-domain geometry, and the molecular geometry of each.
c. Identify the approximate bond angles of each species.
d. Predict which, if any, is a polar species. Justify your answer.
e. Predict the most probable oxidation number of the iodine atom in each species. Give an example of another chemical species having the same oxidation number as IF4+.
f. Would you expect that the conversion of IF5 to IF4+ to be exothermic or endothermic? Explain.
