Question

Compare the molecular shape and hybrid orbitals of PF3 and PF5 molecules

Answer 1

PF3 is phosphorustrifluoride with p in the center and three f bonding with it.PF5 is phosphoruspentafluoride with p in the middle and 5 f linking to bond

Answer 2

Explanation:

The phosphorus trifluoride ($PF_3$) has a piramidal geometry as can be seen in the First figure with the three F bonded to the P.

The phosphorus pentafluoride ($PF_5$) has a bipiramidal geometry as can be seen in the Second figure with all the F bonded to the P.
