  1. Lewis acid-base theory

  2. Lewis acid-base theory Very different from Brønsted-Lowrey acid-base.

  3. Lewis acid-base theory Very different from Brønsted-Lowrey acid-base. Not dependent on protons or pH.

  4. Lewis acid-base theory Definitions: An acid is a lone-pair acceptor.

  5. Lewis acid-base theory Definitions: An acid is a lone-pair acceptor. H+ no electrons – by accepting 2 electrons it attains noble gas configuration.

  6. Lewis acid-base theory An acid is a lone-pair acceptor. H+ no electrons – by accepting 2 electrons it attains noble gas configuration. BF3 electron deficient compound - B needs 2 electrons for noble gas configuration.

  7. B Group III 3 valence electrons

  8. B Group III 3 valence electrons F Group VII 7 valence electrons

  9. B Group III 3 valence electrons F Group VII 7 valence electrons

  10. 6 electrons for boron rather than 8 Lewis Acid

  11. Lewis acid-base theory Definitions: Lewis base: lone-pair donor

  12. Lewis acid-base theory Definitions: Lewis base: lone-pair donor NH3 N has lone pair
