Unit: Resonance and acid-base chemistry
Aspiring chemists need to be able to count electrons. Without this ability, your days as a chemist would be numbered. In this tutorial, you will learn how to count electrons to assign formal charges and oxidation states. Both forms of "electron bookkeeping" are important concepts to understand for organic reactions.
Are bond-line drawings not resonating with you? Sometimes one drawing is not enough to accurately describe the distribution of electron density. In this tutorial, we will learn how two or more resonance structures are merged to give us a single representation (a resonance hybrid).
Do you remember the basics of acid-base chemistry? If your answer is neutral, then you might want to watch this tutorial and review these important concepts from general chemistry.
