Is the O3 Molecule Polar Due to Fractional Charges and Nonlinear Geometry?

Click For Summary
SUMMARY

The O3 molecule, or ozone, is definitively polar due to its nonlinear geometry and the presence of fractional charges on the oxygen atoms. The symmetry group of ozone is C2v, which indicates that the dipole moment along the C2 axis is non-zero, while dipole moments in perpendicular directions are zero. The differing oxidation states of the oxygen atoms contribute to the unequal distribution of charge, reinforcing the molecule's polar nature.

Is O3 molecule polar or non-polar? I am confused. If it is molar, could you explain why?
Thinking you.
 
Chemistry news on Phys.org
Ozone has symmetry group C2v. That means that the dipole moment along the C2 axis is non-vanishing in general, while the dipole moments in directions perpendicular to this direction must be 0.
 
Oxygen atoms are in different states of oxidation. Their fractional charges are different. Molecular geometry is nonlinear.
Hence, dipolar momentum is non-vanishing.
