Do intermolecular forces occur within a single molecule or between two or more separate molecules?

• A. Within a single molecule
• B. Only in metallic bonds
• C. Only within ionic compounds
• D. Between two or more separate molecules

Answer: (D)

Verified step by step guidance

1. Understand the definition of intermolecular forces: these are forces of attraction or repulsion that occur between molecules, not within a single molecule.
2. Recall that intramolecular forces are the forces that hold atoms together within a molecule, such as covalent or ionic bonds.
3. Recognize that intermolecular forces include types like hydrogen bonding, dipole-dipole interactions, and London dispersion forces, all of which act between separate molecules.
4. Note that metallic bonds and ionic bonds are types of intramolecular forces within metals and ionic compounds, respectively, not intermolecular forces.
5. Conclude that intermolecular forces occur between two or more separate molecules, influencing properties like boiling point and solubility.
