Which of the following is NOT an example of an intermolecular force between molecules?

• A. London dispersion forces
• B. Ionic bonding
• C. Hydrogen bonding
• D. Dipole-dipole interactions

Answer: (B)

Verified step by step guidance

1. Step 1: Understand what intermolecular forces are. Intermolecular forces are forces of attraction or repulsion that act between neighboring molecules, affecting properties like boiling point and solubility.
2. Step 2: Review the given options and identify which are intermolecular forces: London dispersion forces, hydrogen bonding, and dipole-dipole interactions are all types of intermolecular forces.
3. Step 3: Recognize that ionic bonding is a type of intramolecular force, meaning it occurs within a compound between ions, not between separate molecules.
4. Step 4: Conclude that ionic bonding is NOT an example of an intermolecular force because it involves electrostatic attraction between ions in an ionic compound, not between molecules.
5. Step 5: Therefore, the correct answer is the option that represents a force not acting between molecules, which is ionic bonding.
