Intermolecular force refers to the force that exists between two or more molecules.
Intermolecular force of attraction is maximum in solids.
This is because molecules in solid remain very close to each other which allot a definite shape to the objects that are solid.
It is lesser in liquids and least in the gases.

Intermolecular forces are maximum in solids and minimum in gases.
Explanation:
Intermolecular forces are the forces of attraction between molecules. They play a significant role in determining the physical properties of substances, such as boiling point, melting point, and solubility. The strength of these forces varies depending on the state of matter - solid, liquid, or gas.
Intermolecular forces in solids:
In solids, the intermolecular forces are the strongest among the three states of matter. This is because the molecules in solids are closely packed together in a highly ordered arrangement. The strong intermolecular forces hold the particles together, resulting in a rigid structure with a definite shape and volume. Examples of intermolecular forces in solids include ionic bonds, metallic bonds, and covalent bonds.
Intermolecular forces in liquids:
In liquids, the intermolecular forces are weaker compared to solids but stronger than gases. The particles in liquids are still close together, but they have enough energy to move around and slide past each other. The intermolecular forces in liquids allow them to have a definite volume but not a definite shape. Examples of intermolecular forces in liquids include dipole-dipole interactions and hydrogen bonding.
Intermolecular forces in gases:
In gases, the intermolecular forces are the weakest among the three states of matter. The particles in gases are far apart and move freely in all directions. The intermolecular forces in gases are so weak that they can be easily overcome by thermal energy, resulting in a lack of definite shape or volume. Examples of intermolecular forces in gases include London dispersion forces and weak van der Waals forces.
Conclusion:
In summary, intermolecular forces are maximum in solids, intermediate in liquids, and minimum in gases. This is because the strength of intermolecular forces depends on the distance between molecules and the nature of the interactions between them. Solids have the strongest intermolecular forces because their particles are closely packed together, while gases have the weakest intermolecular forces due to the large distances between particles.
