• D. Ion-induced dipole forces

Answer: (C)

Verified step by step guidance

1. Step 1: Understand the types of intermolecular forces listed: London dispersion forces, dipole-dipole interactions, hydrogen bonding, and ion-induced dipole forces. Each represents a different kind of attraction between molecules or ions.
2. Step 2: Recall that London dispersion forces are the weakest and arise from temporary fluctuations in electron distribution, present in all molecules but especially significant in nonpolar molecules.
3. Step 3: Recognize that dipole-dipole interactions occur between polar molecules where permanent dipoles attract each other, generally stronger than London dispersion forces.
4. Step 4: Know that hydrogen bonding is a special, stronger type of dipole-dipole interaction that occurs when hydrogen is bonded to highly electronegative atoms like nitrogen, oxygen, or fluorine, leading to particularly strong attractions.
5. Step 5: Understand that ion-induced dipole forces involve an ion inducing a dipole in a nonpolar molecule, which can be strong but typically not as strong as hydrogen bonding between neutral molecules.
