When NaCl dissolves in water, aqueous Na⁺and Cl^-ions result. The force of attraction that exists between Na⁺and H₂O is called a(n) _ interaction. A) ion- dipole B) hydrogen bonding C) ion- ion D) London dispersion force E) dipole- dipole

Question

Quizplus · Accepted Answer

When NaCl dissolves in water, Na+ and Cl- ions are surrounded by water molecules due to the electrostatic attraction between the charged ions and the partially negative oxygen atoms in water molecules. This interaction between the ions and the polar water molecules is called an ion-dipole interaction. The other options (B) hydrogen bonding, (C) ion-ion, (D) London dispersion force, and (E) dipole-dipole interactions can be present in other types of compounds, but in this case, the dominant force responsible for the solubility of NaCl in water is the ion-dipole interaction.
