MOLECULAR POLARITYFIELD NOTE 166 / 175
Is SO2F2 polar or nonpolar?
SO2F2 is polar because its two S=O and two S–F bonds do not sum to zero.

Why SO2F2 is polar
The sulfur center has four ligand directions but two oxygen and two fluorine substituents. Their bond dipoles are not four equivalent vectors, and the measured molecule has a permanent dipole.
What to notice
The shape around S resembles a tetrahedron, but SO2F2 is unlike fully symmetric SF6. NIST lists an experimental dipole of 1.12 D for sulfuryl fluoride.
Common questions about SO2F2
- 01
What does the Lewis structure of SO2F2 show?

What is the molar mass of SO2F2?
SO2F2 has an approximate molar mass of 102.05 g/mol, calculated from its formula using abridged standard atomic weights. Natural isotope variation can change the last digits.
