Construct the Molecule IF₅ and PF₅ using a Molecular Modeling

question 15

Multiple Choice

Construct the molecule IF₅ and PF₅ using a molecular modeling software such as Spartan or 3D-ChemDraw. How do the molecular shapes 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 IF₅ is square pyramidal and PF₅ is trigonal bipyramidal.
• B) In PF₅ there is a lone pair of electrons on phosphorus where as in IF₅ there are no lone pairs on iodine. As a result, the molecular shape of PF₅ is square pyramidal and IF₅ is trigonal bipyramidal.
• C) 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 IF₅ is octahedral and PF₅ is trigonal bipyramidal.
