Which one of the following is the correct definition of intermolecular forces?The forces that are present between molecules.The forces that hold atoms together in a molecule.The forces of attraction between oppositely charged particles.The forces of electrostatic attraction that form between oppositely charged ions.

The correct definition of intermolecular forces is "The forces that are present between molecules."

Here's why:

1. Intermolecular forces refer to the forces of attraction that exist between molecules. These forces are responsible for many of the physical properties of substances, such as boiling and melting points, phase changes, and the physical state of a substance at room temperature.

2. The forces that hold atoms together in a molecule are called intramolecular forces, not intermolecular forces. Intramolecular forces are the forces that keep the atoms in a molecule together.

3. The forces of attraction between oppositely charged particles can refer to a variety of forces, including both intermolecular and intramolecular forces. However, this is not specific enough to be a correct definition of intermolecular forces.

4. The forces of electrostatic attraction that form between oppositely charged ions are called ionic bonds, which are a type of intramolecular force, not intermolecular forces.
