Which one of the following involves ion-dipole interactions? A) Na⁺ and Cl^- B) H⁺ and F^- C) Na⁺ and Mg²⁺ D) two water molecules E) Na⁺ and H₂O

Question

Quizplus · Accepted Answer

Ion-dipole interactions occur between an ion and a polar molecule. In choice E, there is an ion (Na+) and a polar molecule (H2O), therefore this choice involves ion-dipole interactions. The other choices do not involve a polar molecule or a strong enough ion to form ion-dipole interactions.
