Question: When you look at different compounds, how do you know which one is stronger or weaker Lewis acid or base?
For instance, BF3 and BCL3, how do I know which one's stronger? Also is it any different with Lewis bases?

Classifying Chemical Reactions

  • Distinguish different types of chemical reactions including:

  • Combustion – burning C,H,O compounds in oxygen

  • Exchange reactions; partners – ions – change places in ionic compounds

  • Acids – contain hydrogen which can generate H+

  • Bases – react with H+ - and may generate OH-

  • Redox – reduction + oxidation- reactions: electrons transferred between reagents
