Compare the structure of CO and SO. Which of them has a greater dipole moment and why? SO has a greater dipole because the bond dipoles do not cancel in that molecule. CO has a greater dipole because the electronegativity difference between carbon and oxygen is greater than that between sulfur and oxygen. Neither molecule has a dipole moment. CO has a greater dipole because the carbon is sp hybridized, and it forms shorter bonds with more negative charge on oxygens. SO has a greater dipole because one can write several resonance forms that show charge separation Previous Next
