The intermolecular force of H₂CO is dipole-dipole force.

Dipole-dipole force as an intermolecular force

Dipole-dipole forces are attractive intermolecular forces that exist between the positive end of one polar molecule and the negative end of another polar molecule.

  • In order for dipole-dipole forces to be present, a molecule must be polar.  
  • The positive end of one molecule is attracted to the partial negative end of another

H₂CO as a polar molecule

H₂CO is a polar molecule due to the differences in the electronegativity of carbon and oxygen.

Oxygen is more electronegative than carbon, hence, some negative charge is induced on the oxygen atom and a partial positive charge is induced on the carbon atom.

The induced positive and negative charges generates the dipole moment directed from carbon to oxygen atom.

Therefore, molecules of H₂CO are held together by dipole-dipole attractions between the oxygen and carbon atoms.
