BNG_Resonance Lesson

Resonance

Sometimes having just one Lewis structure for a compound is insufficient. In these cases, a resonance structure  is created. Resonance is the concept that no one Lewis structure actually exists, rather an average of more than one Lewis structures. This average is known as the  resonance hybrid. Resonance structures are drawn with a double headed arrow between them to show the contributing factor of each. Molecules that exist in resonance show an increased stability. This is known as the resonance energy.

Be sure to complete the practice problems at the end of the slideshow.

 

In this video, benzene, an organic molecule that displays resonance, and carbonate, a polyatomic ion that displays resonance, are studied.

Remember to work on the module practice problems as you complete each section of content.
