What is the predominant intermolecular force (dipole-dipole, dispersion, or hydrogen bonding) in each of these compounds: hydrogen fluoride, carbon tetrafluoride, and hydrogen chloride?
The method used in this experiment is sometimes called the vapor density method. Beginning with ideal gas equation, show how the density of a vapor may be determined by this method.
