According to VSEPR theory, the electron groups around the central atom (P) will arrange themselves to be as far apart as possible, which will determine the bond angles. In PF₅, there are four electron groups around P: three F atoms and one lone pair. The lone pair will occupy more space than the F atoms, so it will exert a greater repulsive force on the F atoms, pushing them slightly closer together. This results in the following bond angles: - 90F1F1F1S1F1F1F10 (between each F and the lone pair) - 120F1F1F1S1F1F1F10 (between each F and the other two F atoms) - 180F1F1F1S1F1F1F10 (between the two F atoms opposite each other) Therefore, choice C is the best choice as it includes all three predicted bond angles according to VSEPR theory.
