Presentation Transcript

  1. 8. Lewis Acid/Bases: definition - acids are electron pair acceptors; bases are electron pair donors • Lewis acids: • cations; H1+, compounds with empty p-orbitals (CO2, BF3); H in H2O • Lewis bases: • anions, nitrogen bases, O2-, • reactions: use curved arrows to show “movement” of electrons • examples • 1. NH3+BF3F3BNH3 • 2. Na2O(aq)+H2O(l)  Chapter 15 Notes

  2. 8. Lewis Acid/Bases: examples • 3. H1-(aq)+H2O(l) • 4. CO2(aq)+H2O(l)  • 5. SO3+H2O  Chapter 15 Notes
