Witryna29 maj 2024 · There are basically 3 - dipole/dipole, London Dispersion, and H-Bonds. The length of the alcohol basically determines whether or not they associate with water. Short chain alcohols have intermolecular forces that are dominated by H-bonds and dipole/dipole, so they dissolve in water readily (infinitely for methanol and ethanol). … WitrynaDue to its smaller size, ethanol exhibits weaker dispersion forces than diethyl ether. However, ethanol is capable of hydrogen bonding and, therefore, exhibits stronger overall IMFs, which means that fewer molecules escape from the liquid at any given temperature, and so ethanol has a lower vapor pressure than diethyl ether.
