Answer:
hydrogen bonding
Step-by-step explanation:
Carboxylic acid molecules are capable of forming hydrogen bonds between their hydrogen and oxygen atoms. This is due to the presence of a highly electronegative oxygen atom attached to a hydrogen atom, as well as the availability of a lone pair of electrons on the oxygen atom.
The hydrogen bonding between carboxylic acid molecules is relatively strong and contributes to their high boiling points and solubility in water. Additionally, carboxylic acids can also participate in dipole-dipole interactions and London dispersion forces with other molecules, depending on their size and shape.
Therefore, the intermolecular bonding that occurs between carboxylic acid molecules includes hydrogen bonding, as well as other types of weaker intermolecular forces.
