The "Lewisiana" Purchase Video

Postby Simone Seliger 1C » Wed Nov 18, 2015 2:41 pm

This video covers the process of how to determine Lewis structures for both ionic and covalent bonds. It also explains the exceptions of the process, resonance, and formal charge.

Our video details how to draw lewis structures based on the amount of electrons present in the molecule and formal charge. We also briefly discussed resonance

The video gives the basics of Lewis Structures and the rules in boding and some anomalies that are present. It also covers resonance and formal charge.

Good video! One small point to clarify: in the ethylene example, each carbon atom in theory could accommodate another lone pair, giving each carbon an octet. The reason that can't be done is because then the molecule would have 14 electrons while there were only 12 to work with in the first place. That's why a double bond was necessary.

Of course, I was thinking that wasn't right when we were filming! Sorry for the mistake.
