Lewis Dot Diagrams 3: Complex Molecules

Author: Katie Smith
Description:

To understand how to draw a Lewis Dot structure for a molecule containing double bonds.
To understand how to draw a Lewis Dot structure for a molecule containing triple bonds.
To understand how to draw a Lewis Dot structure for a molecule with multiple resonance structures.
To understand how to draw a Lewis Dot structure for a polyatomic ion.

In this packet, a video and practice problems review how to draw Lewis Dot diagrams for complex molecules and ions, including those containing double and triple bonds, those with resonance structures, and polyatomic ions.

Tutorial

Lewis Dot Diagrams

At this point, we've looked at how to draw a Lewis dot diagram for individual elements as well as for simple molecules.  (If you've forgotten, or if you skipped that step, click on the links above to review!)  The final step is to create structures and drawings for more complicated molecules, such as those with multiple bonds or those with resonance structures.

Drawing Lewis Dot Structures

This video will review what you've learned about writing a Lewis Dot structure for a simple molecule and expand the rules to include molecules containing double and triple bonds, those with resonance structures, and polyatomic ions.
