The strongest attractive forces between molecules of H2O are

The strongest attractive forces between molecules of H_2O are: ionic covalent hydrogen bonding dipole-dipole attractions dispersion forces

Solution

Water molecules are held strong by hydrogen bond (electrostatic attraction). Due to this strong bond only water is in liquid state.

Even though ionic and co valent bonds are stronger than hydrogen bond , in water two hydrogen\'s are held together by strong hydrogen bond (electrostatic attraction between two polar molecules).
