Step 1 - Understanding intermolecular forces and chemical bonds
There are two main interactions in chemistry: intermolecular forces and chemical bonds. The main difference between them is the distance between the atoms that are interacting.
A chemical bond may be ionic, covalent or metallic. It happens within the atoms or ions in a molecule. It thus keeps a molecule together.
Intermolecular forces, on the contrary, operate at higher distances, and they may be dipole-dipole or nonpolar interactions. They keep molecules together.
Let's take, as an example, the molecule of water:
As we know, the molecule of water is H2O, two H atoms and one O atom. The O-H atoms are bonded together. This is a chemical bond. But in a glass of water, as we could expect, there are over 10^23 molecules of water. They are kept together by an intermolecular force: hydrogen bonding.
Step 2 - Checking whether the statement is true
As we have seen in step 1, intermolecular forces do are forces of attraction between molecules. The statement is thus true.
