# Predict which of the solutions below will exert the highest Vapor pressure

## Homework Statement

Hi I have a question. Predict which of the solutions below will exert the highest Vapor pressure

O2 in HOH
NH3 in HOH
and CH3OH in HOH

## Homework Equations

I drew them out. So I know that CH3OH HOH exhibits h bonding. So does NH3 HOH
I was wondering about O2 and HOH. I think it does. Am I right? I don't care about the actual question right now or if I'm on the right parth with that I just want to know if O2 and HOH have h bonding. Thank you

## The Attempt at a Solution

$NH_{3}$ does not exhibit H- bonding per se.
$NH_{3}+H-OH -->NH_{4}^+ +OH^-$
