SUMMARY
The discussion focuses on predicting which solution will exert the highest vapor pressure among O2 in water (HOH), NH3 in water, and CH3OH in water. It is established that CH3OH and NH3 both exhibit hydrogen bonding, which typically lowers vapor pressure. O2 does not participate in hydrogen bonding with water, leading to a higher vapor pressure compared to the other two solutions. Therefore, O2 in water is predicted to have the highest vapor pressure.
