Trey Moses · Answer 1

We know that the greater the difference is in electronegativity between the atoms which holds the molecule, the greater the polarity is the bonds between them.

Since we know that F has the highest electronegativity among all the elements, therefore PF3 has more polar bonds than PCl3.
