H₂O has dipole moment while CO₂ does not have dipole moment because:

  • Water and carbon dioxide have different molecular structures, which explains the reason.
  • Water is a polar molecule that typically has a dipole moment due to electronegativity differences between its atoms, but CO₂ forms a non-polar bond.
  • However, the structure of the H₂O molecule is twisted due to the presence of a lone pair of electrons on oxygen atoms. As a result, it has a net dipole moment and does not cancel the charges on the atom.
  • There is no lone pair on the carbon atom in the CO₂ molecule, thus it forms covalent bonds with oxygen atoms. It takes the shape of a linear structure and cancels the charge on atoms with a dipole moment of zero.
  • H₂O possesses a dipole moment due to its structure and lone pair of electrons, but CO₂ does not.
