In water, the primary intermolecular forces present are hydrogen bonding, dipole-dipole interactions, and London dispersion forces.1. Hydrogen bonding: This is the strongest intermolecular force in water. It occurs between the highly electronegative oxygen atom and the hydrogen atom of another water molecule. The partial negative charge on the oxygen atom attracts the partial positive charge on the hydrogen atom, forming a hydrogen bond.2. Dipole-dipole interactions: Water molecules have a bent molecular geometry, which results in a polar molecule with a net dipole moment. The positive end of one water molecule is attracted to the negative end of another water molecule, creating a dipole-dipole interaction.3. London dispersion forces: These are the weakest intermolecular forces and are present in all molecules, including water. They arise due to temporary fluctuations in electron distribution around the molecules, which create temporary dipoles that attract other molecules.
