... b) Is the PF3 molecular polar, or is it nonpolar? Explain. The PF3 molecule is polar because it has an electronegativity difference of 1.8 (well above the 0.45 cut off point) and the molecule is not symmetrical due to the lone pair on the phosphorus. c) On the basis of bonding principles, predict wh ...
