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

Click For Summary
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.

PREREQUISITES
  • Understanding of vapor pressure concepts
  • Knowledge of hydrogen bonding and its effects on physical properties
  • Familiarity with molecular structures of O2, NH3, and CH3OH
  • Basic principles of solution chemistry
NEXT STEPS
  • Research the effects of hydrogen bonding on vapor pressure in solutions
  • Study the molecular interactions between water and nonpolar molecules
  • Learn about the Raoult's Law and its application in predicting vapor pressures
  • Explore the concept of colligative properties in solution chemistry
USEFUL FOR

Chemistry students, educators, and anyone interested in understanding the effects of molecular interactions on vapor pressure in solutions.

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

 
Physics news on Phys.org
##NH_{3}## does not exhibit H- bonding per se.
##NH_{3}+H-OH -->NH_{4}^+ +OH^-##
 
Why can you explain? I don't understand your reason. NH3 to a lone pair on O2...seems like H bond to me.
