(1) In which liquid are the intermolecular attractive forces the weakest ?
(2) Which liquid would be expected to have the highest vapor pressure at 42.3 °C?
Expert Solution
Step 1
The vapor pressure of a liquid is directly related to the intermolecular forces . The stronger these forces, the lower the rate of evaporation and the lower the vapor pressure.
