MOLECULAR POLARITYFIELD NOTE 148 / 175
Is OF2 polar or nonpolar?
OF2 is polar because its two O–F bonds form a bent arrangement and their dipoles do not cancel.

Why OF2 is polar
Oxygen difluoride has a bent geometry with oxygen at center. Fluorine (3.98) is more electronegative than oxygen (3.44) and pulls electrons outward toward the fluorines, partially opposing the oxygen lone pair contribution.
What to notice
Fluorine pulls electron density away from oxygen in OF2. The bent shape stops the two O–F bond dipoles from canceling.
Common questions about OF2
- 01
What does the Lewis structure of OF2 show?
O forms two single O–F bonds and keeps two lone pairs. Each F has three lone pairs.
