melting points and boiling points. Not all molecules containing polar bonds are polar. The polar bonds must be unevenly dispersed in the molecule in order to produce a polar molecule. CO2 and CBr4, for example, have polar bonds but are not polar molecules. The third type of intermolecular force is hydrogen bonding, a specific type of dipole- At the normal boiling point of a liquid, the vapor pressure is equal to the standard atmospheric pressure defined as 1 atmosphere, 760 Torr, 101.325 kPa, or 14.69595 psi. For example, at any given temperature, methyl chloride has the highest vapor pressure of any of the liquids in the chart.
