Assuming you mean. Formaldehyde has a dipole moment, and is very polar. CH2O, IUPAC name methanal, common name formaldehyde is polar. Section 2-9. Polar molecules also form when the spatial arrangement of chemical bonds leads to a more positive charge on one side of the molecule than the other. In both molecules, the oxygen atoms attract electrons more strongly than the carbon or hydrogen atoms do. More electronegative atom attracts the shared … Formaldehyde has a polar carbon-oxygen double bond, and is not symmetrical. Add about 2 tablespoons of water to one cup and 2 tablespoons of vinegar to the other. … Is formaldehyde polar or non polar? Carbon dioxide is nonpolar.
