Resonance and acid-base chemistry

This course is a part of Organic chemistry, a 14-course Topic series from Khan Academy.

Let's review how to keep track of electrons using formal charges, oxidation states, oxidation-reduction reactions, and resonance structures. We will also go over the principles of acid-base chemistry.

This course contains 3 segments:

Counting electrons

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.

Resonance structures

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).

Organic acid-base chemistry

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.
