C
Ionic bonding
D
Nuclear force
Verified step by step guidance1
Understand that intermolecular forces are forces that occur between molecules, affecting properties like boiling and melting points.
Recognize that covalent bonding and ionic bonding are types of intramolecular forces, meaning they hold atoms together within a molecule or compound, not between molecules.
Note that nuclear force is a force that acts within the nucleus of an atom, not between molecules.
Identify hydrogen bonding as a specific type of intermolecular force that occurs when a hydrogen atom is attracted to a highly electronegative atom (like oxygen, nitrogen, or fluorine) in a nearby molecule.
Conclude that among the given options, hydrogen bonding is the correct term that identifies a type of intermolecular force.
