"WebC=O has a larger dipole moment than C=C, meaning C=O has a stronger bond strength. This is because of the difference in electronegativity values of C and O. As you already know, a greater mass of the atoms of a bond means a lower frequency. But C=O has a greater bond strength, which apparently compensates for the difference in mass.
