One would expect dipole-dipole interactions, dispersion forces, and hydrogen bonding in this molecule (butyric acid). The COOH group is polar, hence dipole interaction, and the H on the OH of this molecule is available for hydrogen bonding. As with all other molecules, the weaker dispersion forces are also present.
Butanoic acid, like all carboxylic acids has a relatively high boiling point because it is hydrogen bonded. This is attraction between the lone pair of the slightly negative oxygen atom of the carboxyl group on one molecule and the slightly positive hydrogen of the carboxyl group of the next. There is also some dipole-dipole attraction and van der Waals forces.
dipole-dipole dispersion
dipole forces and induced dipole forces
Ammonia form hydrogen bonds.
These are polar forces, intermolecular forces of attraction between molecules.
intERmolecular means between molecules IntRAmolecular means within A molecule.

Intermolecular describes the interactions between separate molecules.
A volatile liquid is easy to vaporize because there are weak intermolecular attractions between its molecules. A nonvolatile liquid is difficult to vaporize because there are strong intermolecular attractions between its molecules.
These are polar forces, intermolecular forces of attraction between molecules.
intERmolecular means between molecules IntRAmolecular means within A molecule.
Intermolecular spaces refer to the empty spaces or gaps between molecules in a substance. These spaces determine the physical properties of the substance, such as density and compressibility. The size of intermolecular spaces can affect how closely packed molecules are in a material.
The intermolecular bonds between water molecules are hydrogen bonds.
