Is PF3 polar?
Understand the Problem
The question is asking whether the molecule phosphorus trifluoride (PF3) has a net dipole moment, which indicates if it is polar or nonpolar. We will consider the molecular geometry and electronegativity differences between the atoms to determine polarity.
Answer
PF3 is polar.
Yes, PF3 is polar.
Answer for screen readers
Yes, PF3 is polar.
More Information
The molecule PF3 (phosphorus trifluoride) has a trigonal pyramidal shape, with phosphorus at the center and three fluorine atoms around it. The lone pair of electrons on phosphorus results in an asymmetric distribution of charge, making the molecule polar.
Tips
A common mistake is to ignore the presence of lone pairs on the central atom, which can significantly affect the molecule's shape and polarity.
