9. How do the molecular geometry of the molecule IF5 and PF5 differ?A. In IF5, there is a lone pair of electrons on iodine where as in PF5 there are no lone pairs on phosphorus. As a result, the molecular shape of IF5is square pyramidal and PF5 is trigonal bipyramidal.B. In PF5, there is a lone pair of electrons on phosphorus where as in IF5there are no lone pairs on iodine. As a result, the molecular shape of PF5is square...
