Detailed explanation-1: -Hydrogen Bonds. The attractive force between water molecules is an unusually strong type of dipole-dipole interaction. Water contains hydrogen atoms that are bound to a highly electronegative oxygen atom, making for very polar bonds.

Detailed explanation-2: -Cohesion: Hydrogen Bonds Make Water Sticky In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond.

Detailed explanation-3: -The force of attraction between molecules of a substance is called the intermolecular force of attraction.

Detailed explanation-4: -Dipole-dipole forces are attractive forces between the positive end of one polar molecule and the negative end of another polar molecule. Dipole-dipole forces have strengths that range from 5 kJ to 20 kJ per mole.
