An increase in disorder always results when a solution forms. CH4 is completely symmetrical, so it is non polar. Atoms/molecules are polarizable to a degree, so you'll get some interactions from them when you bring them together as the electro. Ionion attractions are much stronger than any intermolecular force. (Use the appropriate less than, =, or greater than symbol to separate substances in the list.) Boiling points reflect the strength of intermolecular force. So 9. Its strongest intermolecular forces are London dispersion forces. One of these (CH3COOH) has the ability to hydrogen-bond. The following is the order from lowest boiling point to highest based on the types of forces these compounds have: $\ce{CO2}$ - dispersion forces $\ce{CH3Br}$ - dispersion and dipole-dipole $\ce{CH3OH}$ - dispersion, dipole-dipole, and hydrogen bonding $\ce{RbF}$ - ionic What types of intermolecular forces are found in these molecules. a. Higher surface tension corresponds to stronger intermolecular forces. Answer (1 of 5): It should have dipole dipole, hydrogen bonding, and Van Der Waals (London Dispersion) forces. london dispersion if we place an ion or a polar moleculenear an atom (or a nonpolar molecule),the electron distribution of the atom (ormolecule) is distorted by the forceexerted by the ion or the polarmolecule, resulting in a kind of dipole.
