Select the type of interaction which best describes the attraction between Mg2 + ions and water molecules.

A) dipole-dipole

B) dipole-induced dipole

C) ion-dipole

D) ion-induced dipole

E) ion-hydrogen bond

C) ion-dipole

Explanation:

Ion - dipole interaction -

These type of interactions are observed, simply by an ionic species, and the species which can for a dipole, is referred to as the ion - dipole interactions.

Dipole - It refers to the species, which is capable to generate two poles, i. e. a delta positive and a delta negative, is referred to as a dipole.

For example,

In water, due to more electronegative oxygen, it attains a delta negative charge and correspondingly, hydrogen attains a delta positive charge, and therefore, forms a dipole.

From the question,

Mg²⁺ is an ionic species, and water can form a dipole, and hence, the interaction possible between the two species is ion - dipole interaction.
