MOLECULAR POLARITYFIELD NOTE 97 / 175
Is COF2 polar or nonpolar?
COF2 is polar because one C=O bond and two C–F bonds do not balance in its planar three-bond arrangement.

Why COF2 is polar
Carbon has three bonding regions: a carbonyl oxygen and two fluorines. The two C–F contributions are symmetric with each other but are not an equal opposite to the C=O bond, so the net dipole survives.
What to notice
A trigonal planar label specifies approximately 120° directions, not identical bonds. COF2 differs from symmetric BF3 because its three arms are not alike.
Common questions about COF2
- 01
What does the Lewis structure of COF2 show?
The common Lewis structure is F–C(=O)–F. Oxygen has two lone pairs and each fluorine has three.
- 02
What is the molecular geometry of COF2?
COF2 has a trigonal planar molecular geometry. The 3D model shows representative bond angles of 120.2° and 119.9°. These angles come from the displayed model coordinates.
