Is Significant Hydrogen Bonding Possible in Phosphine (PH3)?

Click For Summary
SUMMARY

Significant hydrogen bonding in phosphine (PH3) is not feasible due to the molecular structure and electronegativity of phosphorus. Phosphorus has five valence electrons, three of which form covalent bonds with hydrogen atoms, leaving two non-bonding electrons. These non-bonding electrons do not facilitate hydrogen bonding effectively, as phosphorus has a lower electronegativity compared to other elements typically involved in hydrogen bonding, such as nitrogen or oxygen.

PREREQUISITES
  • Understanding of molecular bonding, specifically covalent and ionic bonds.
  • Knowledge of electronegativity and its role in chemical interactions.
  • Familiarity with the molecular structure of phosphine (PH3).
  • Basic concepts of hydrogen bonding and its requirements.
NEXT STEPS
  • Research the electronegativity values of phosphorus compared to nitrogen and oxygen.
  • Explore the molecular geometry of phosphine and its implications for bonding.
  • Study hydrogen bonding in other molecules, such as ammonia (NH3) and water (H2O).
  • Investigate the role of lone pairs in molecular interactions and bonding capabilities.
USEFUL FOR

Chemistry students, educators, and researchers interested in molecular bonding and the properties of phosphine.

Homework Statement



is significant hydorgen bonding possible in phosphine, PH3

The Attempt at a Solution



The text says no, I don't see why not. P has 5 electrons in its outer shells, 3 of those form an ionic bond with the 3 H. That leaves 2 non-binding electrons, those 2 non-binding electrons will be attracted to the other Hydrogens in the substance.
