Is XeO2F2 A Polar Molecule?

Yes, XeO2F2 is a polar molecule.

This is because the molecule has a bent molecular geometry due to the presence of two lone pairs on the central xenon atom and the highly electronegative fluorine atoms on either side. This results in an uneven distribution of electrons within the molecule, creating a partial positive charge on the xenon atom and partial negative charges on the fluorine atoms. As a result, the molecule has a net dipole moment and is considered polar.
