Question

Quizplus · Accepted Answer

P in PF3 has 5 valence electrons, and F has 7 valence electrons each. In PF3, the 3 F atoms form a plane with an angle of 120 degrees between each other, and the P atom is situated above the plane with a bond angle of about 107 degrees. Therefore, the electron geometry is tetrahedral (four bond pairs) and the molecular geometry is trigonal pyramidal (three bond pairs and one lone pair). Option D is the only molecule that fits this description.
