I'm trying to understand what exactly the term high and low vapor pressure refer to. Methanol vs Ethanol vs Hexane The intermolecular forces between Ethanol is higher than that of methanol (greater dispersion forces, so more intermolecular bond) At an given temp, ethanol will vaporize less easily than methanol. Similary, at a given temp, hexane will reach the vapor pressure equlibrium more easily. Now my question is, Does Ethanol have a lower VP?? (at a given temp, it less easily vaporizes and needs more KE or time, if it is been heated to reach the surrounding atmospheric pressure) When we say low vapor pressure, we simply mean that a particular solute has less tendency to evaporate? Its more strongly held in solution. Addtionally, if I add some hexane in ethanol, the vapor pressure will further decrease. The basic premise is that Ethanol has lower VP, higher BP, more stable?
