8.2 How to Draw Lewis Dot Structures | Complete Guide | General Chemistry

Chad explains and demonstrates exactly how to draw Lewis Dot Structures in this lesson including numerous examples. The octet rule is introduced and explained followed by the three notable exceptions including expanded octets. How to easily calculate formal charge is also included as well as how to draw multiple resonance structures for certain molecules. It is also shown for molecules exhibiting resonance how to use formal charge to distinguish between individual resonance structures. The Lewis Dot Structures for a large number of molecules are worked out for students including CCl4, NF3, HCN, CO2, N2O, SF4, XeF4, SO4^2-, and NO3^-. I've embedded this playlist as a course on my website with all the lessons organized by chapter in a collapsible menu and much of the content from the study guide included on the page.
