Can sodium sulphate, p-toluidine, and benzoic acid form hydrogen bond

Click For Summary

Discussion Overview

The discussion centers around the potential for sodium sulphate, p-toluidine, and benzoic acid to form hydrogen bonds with water. It explores the requirements for hydrogen bonding and the specific functional groups present in these compounds that may facilitate such interactions.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant questions whether sodium sulphate, p-toluidine, and benzoic acid can form hydrogen bonds with water.
  • Another participant inquires about the requirements for a molecule to act as a hydrogen bond acceptor or donor and whether the discussed compounds meet these criteria.
  • A participant suggests that the presence of oxygen in all three compounds implies they may engage in hydrogen bonding with water.
  • It is noted that compounds with lone pairs on oxygen can be hydrogen bond acceptors, and that p-toluidine has an amine group capable of acting as both a hydrogen bond donor and acceptor. Additionally, the -OH groups in p-toluidine and benzoic acid are mentioned as potential hydrogen bond donors.

Areas of Agreement / Disagreement

Participants express varying viewpoints on the hydrogen bonding capabilities of the compounds in question, indicating that the discussion remains unresolved regarding the specifics of their interactions with water.

Contextual Notes

The discussion does not clarify the specific conditions under which hydrogen bonding may occur, nor does it resolve the implications of the functional groups present in the compounds.

can sodium sulphate, p-toluidine, and benzoic acid form hydrogen bond with water?
 
Physics news on Phys.org


What are the requirements for being a hydrogen bond acceptor or donor? Do these compounds fulfill those requirements?
 


do they all have h-bonds with water because they all contain O?
 


Yes, compounds with lone pairs on an oxygen atom are capable of being hydrogen bond acceptors and can hydrogen bond with water. The compounds contain other hdyrogen bond donors and acceptors as well. The amine group on p-toluidine can act as both a hydrogen bond donor and acceptor. Also, the phenolic -OH from p-toluidine and the carboxylic acid -OH of benzoic acid can act as a hydrogen bond donor in addition to being a hydrogen bond acceptor.
