Formaldehyde (HCHO) primarily exhibits dipole-dipole interactions due to its polar nature, as it has a significant difference in electronegativity between the carbon and oxygen atoms. Additionally, it can participate in hydrogen bonding because of the presence of a hydrogen atom attached to the carbon, which is adjacent to the highly electronegative oxygen atom. However, hydrogen bonding in formaldehyde is weaker than in substances like water. Overall, the dominant intermolecular forces in HCHO are dipole-dipole interactions, with some contribution from hydrogen bonding.
Boiling point is a property not a force; but a high boiling point indicate a strong intermolecular force.
Intermolecular attraction
The intermolecular force in Ar (argon) is London dispersion forces, which are the weakest type of intermolecular force. This force is caused by temporary fluctuations in electron distribution around the atom, leading to temporary dipoles.
The physical state of matter with the least intermolecular force is a gas, where particles are far apart and move freely. Conversely, the state with the greatest intermolecular force is a solid, where particles are closely packed in a fixed arrangement. Liquids fall in between, with moderate intermolecular forces allowing for both some degree of particle movement and a defined shape.

intermolecular force
This is an intermolecular force.
In C6H14 (hexane) and H2O (water), there are London dispersion forces, dipole-dipole interactions, and hydrogen bonding. In HCHO (formaldehyde), there are dipole-dipole interactions and London dispersion forces. In C6H5OH (phenol), there are hydrogen bonding, dipole-dipole interactions, and London dispersion forces.
Boiling point is a property not a force; but a high boiling point indicate a strong intermolecular force.

Intramolecular forces are not intermolecular forces !
The intermolecular force in BF3 is London dispersion forces. This is because BF3 is a nonpolar molecule, so the only intermolecular force it experiences is the temporary weak attraction between temporary dipoles.
The physical state of matter with the least intermolecular force is a gas, where particles are far apart and move freely. Conversely, the state with the greatest intermolecular force is a solid, where particles are closely packed in a fixed arrangement. Liquids fall in between, with moderate intermolecular forces allowing for both some degree of particle movement and a defined shape.
