Question

What is the force of attraction between the molecules of a substance called?

Answer 1

• Inter-molecular forces are the force of attraction between molecules of same substances.
• The forces of attraction and repulsion that act between neighbouring particles are known as inter-molecular forces (atoms, molecules, or ions ). In comparison to intramolecular forces like covalent or ionic bonds between atoms in a molecule, these forces are weak.
• Solids have strongest intermolecular forces whereas gases have smallest intermolecular forces between them.
