Which intermolecular forces do you expect to be present in Intermolecular forces: the forces of attraction present in between the molecules or atoms or compounds is termed as intermolecular forces. A liquid with stronger intermolecular forces does not evaporate easily and thus has a lower vapor pressure. WebSee Answer. Hydrogen bonds form when you have a negative O, N, or F atom in one molecule and a positive H atom attached to an O, N, or F atom in another molecule. In CH3Cl, the C-Cl bond is polar. water vapor pressure at 25 C. What is the intermolecular forces of CHCl3?
