**Resonance is a concept that is frequently used in ochem to explain chemical reactivity. This tutorial provides the basics of drawing resonance structures. (Runtime = 14:07)**

**Student Learning Outcomes**

After viewing this tutorial and practicing problems from this website and your textbook, you should be able to:

• Recognize when a resonance structure can be drawn for a chemical structure.

• Be able to rank the relative stabilities of resonance structures.

• Be able to used curved arrow notation to show how electrons are redistributed between resonance structures.

**Practice Problems**

Here are some problems to get you started. You should first try each on a piece of paper. Then, place your cursor over the graphic and click on right arrow that appears to see the answer. The right and left arrows allow you to move back and forth between problems. Please note that these are *not* the only types of problems/questions that exist on this topic. Refer to your textbook and any problems your instructor provides you for more practice with this subject.
