What kind of force acts within a molecule?A.A Van der Waals forceB.An intermolecular forceC.An intramolecular forceD.A nonpolar force

The question is asking about the type of force that acts within a molecule. Let's analyze the options provided:

1. A. Van der Waals force: This refers to the weak attractions between molecules, so it is not the correct answer as it pertains to interactions between molecules rather than within a single molecule.

2. B. An intermolecular force: Intermolecular forces are those that occur between different molecules. Therefore, this does not pertain to forces within a single molecule.

3. C. An intramolecular force: This is the correct choice. Intramolecular forces are the forces that hold the atoms together within a molecule, such as covalent or ionic bonds.

4. D. A nonpolar force: This is not a recognized category related to the forces acting within a molecule.

Final Answer

C. An intramolecular force acts within a molecule.
