How do the molecular geometry of the molecule IF5 and PF5 differ?

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 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.

10. What are the bond angle formed by the central atom P and two of the equatorial fluorine’s in the molecular geometry of PF5?

a. 90°

b. 120°

c. 109.5°
