Does acidity and hydrogen bond strength go hand in hand?

Click For Summary
SUMMARY

The discussion centers on the relationship between acidity and hydrogen bond strength, highlighting that increased acidity correlates with higher electronegativity and dipole moments. Participants noted that while strong acids like hydrochloric acid (HCl) do not exhibit hydrogen bonding, acidic solutions can influence hydrogen bond dynamics when mixed with water. The conversation also referenced acetic acid, which, despite having low surface tension, is classified as an acid, prompting questions about the nature of hydrogen bonds in acidic environments.

PREREQUISITES
  • Understanding of acidity and pH levels
  • Knowledge of hydrogen bonding and molecular interactions
  • Familiarity with dipole moments and electronegativity
  • Basic chemistry concepts regarding acids and bases
NEXT STEPS
  • Research the properties of hydrogen bonds in aqueous solutions
  • Explore the relationship between dipole moments and molecular structure
  • Investigate the behavior of strong acids like hydrochloric acid in various solvents
  • Study the surface tension characteristics of different acids, including acetic acid
USEFUL FOR

Chemistry students, researchers in physical chemistry, and professionals studying molecular interactions and acid-base chemistry will benefit from this discussion.

More acidity means more electronegativity, and more electronegativity means more dipole moments. I observed that liquids with low dipole moments (bases) often have lower density and surface tension, but not necessarily hydrogen bonds. To contradict it, acetic acid have a low surface tension but it's an acid. Does acidity means a stronger hydrogen bond?

What dipoles moments are you thinking of?
Hydrochloric acid (for example) is a strong acid but are there any hydrogen bonds in it? I don't think so.
You mean the H3O+?
 
Sorry for my mistake, I was actually trying to find if an acidic solution when mixed with water would strengthen its hydrogen bonds.
