[19] Rank the following molecules in order of (a) increasing room temperature vapor pressure, and (b) normal boiling point. For each ranking explain your reasoning. 8: benzene 2 pyridine a) Room temperature vapor pressure ranking The definition of vapor pressure: At a given temperature, the vapor pressure of a liquid is the pressure exerted by the vapors or gaseous phase that is in equilibrium with its liquid phase. The relationship between vapor pressure and intermolecular forces: the The vapor pressure of a liquid is inversely proportional to the strength intermolecular forces. Greater is the strength of the intermolecular forces in the molecules in the liquid phase, lower will be the molecules in the gaseous phase above the surface of the liquid, and hence lower will be the vapor pressure. b) Boiling Point Ranking. OH benzoic acid
