Question

What is meant by the inter-molecular forces of attraction ?

Answer 1

INTER-MOLECULAR FORCES OF ATTRACTION : “The forces of attraction between the molecules of matter is called the inter-molecular force of attraction.”
This inter molecular force is maximum in solids, less in liquids and least in gases.

Intermolecular forces are the forces of attraction or repulsion which act between neighboring particles (atoms, molecules, or ions ). These forces are weak compared to the intramolecular forces, such as the covalent or ionic bonds between atoms in a molecule. For example, the covalent bond present within a hydrogen chloride (HCl) molecule is much stronger than any bonds it may form with neighboring molecules.
