dispersion forces
London dispersion force usually pertains to carbon carbon chains. It is a very weak force. For polar molecules the intermolecular force is described as dipole-dipole. Oxygen has a greater electronegativity than sulfur so its dipole-dipole force would be stronger than hydrogen sulfide. Oxygen also has the ability to hydrogen bond which is a pretty strong force.
Nonpolar molecules rely solely on London dispersion forces (LDFs) for their intermolecular interactions. This is significant because LDFs are the weakest type of intermolecular force, resulting in lower boiling and melting points for nonpolar substances compared to polar molecules with stronger intermolecular forces like hydrogen bonding or dipole-dipole interactions.
Intermolecular forces include London dispersion forces, dipole-dipole interactions, and hydrogen bonding. London dispersion forces are the weakest and occur between all molecules. Dipole-dipole interactions exist between polar molecules like HCl. Hydrogen bonding is the strongest intermolecular force and occurs between molecules with hydrogen directly bonded to highly electronegative atoms like in H2O.
The intermolecular forces of attraction present between HCl molecules are primarily dipole-dipole forces due to the difference in electronegativity between hydrogen and chlorine atoms. Additionally, there may be some weak London dispersion forces present between the molecules.
The intermolecular forces between C3H7OH, which is also known as propanol or isopropyl alcohol, include hydrogen bonding and London dispersion forces. The hydrogen bonding occurs between the hydrogen atom of one molecule and the oxygen atom of another molecule. This strong intermolecular force gives propanol a higher boiling point compared to molecules of similar size that do not exhibit hydrogen bonding. Additionally, London dispersion forces, which are weak temporary forces caused by the movement of electrons, also play a role in holding propanol molecules together.

To determine the strongest intermolecular force in a substance, you need to consider the types of molecules present. Look for hydrogen bonding, which is the strongest intermolecular force. If hydrogen bonding is not present, then consider dipole-dipole interactions and London dispersion forces in determining the strength of intermolecular forces.
Hydrogen bonding and London Dispersion forces (the latter of which are in all molecules).
Molecules typically have London dispersion forces (van der Waals forces), dipole-dipole interactions, and hydrogen bonding as types of intermolecular forces (IMF) in chemistry. These forces determine the physical properties of molecules such as boiling points and solubility.
The intermolecular forces present in CH3CH2OCH2CH3 are London dispersion forces, dipole-dipole interactions, and possibly hydrogen bonding between the oxygen atom and hydrogen atoms in neighboring molecules.
The most important intermolecular force between nitrogen gas molecules is London dispersion forces, due to the nonpolar nature of N2. Although weaker than dipole-dipole or hydrogen bonding forces, London dispersion forces are still present in all molecules.
The main intermolecular force holding water molecules together in hydrogen bonding. Also, there are diplole-dipole interactions and London dispersion forces. But hydrogen bonds are the major force keeping water in the liquid state.
