What is the strongest intermolecular force between an NaCl unit and an H2O molecule together in a solution?

Covalent bonding

Dipole-dipole force

Hydrogen bonding

Ion-dipole force

Ion-dipole force

Explanation:

Dipoles are found in the polar molecule. A polar molecule is formed when one atom in the molecule attracts most of the electron cloud (due to its higher atomic number) hence making this side of the molecule partially negative. The other part of the molecule becomes partially positive (forming dipoles). Ionic compound (because they are charged) dissociate in polar solvents and the ions form ion-dipole bonds.
