CHEMISTRY: Happy weekend! Here the short, short lecture from Friday on double and triple covalent bonds, with resonance at the end.

Be careful about getting too happy with double bonding – count electrons and don’t forget CONS. And what else? Oh yes, PRACTICE, PRACTICE, PRACTICE! We’ll put one more twist on Lewis structures Monday!

Homework changed to redo the Lewis Structure worksheet – and work on your project! 🙂
