CHEMISTRY: Great job practicing multiple bonds with Lewis structures today! Here’s the lecture from yesterday 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 tomorrow!

Now go forth and conquer the Lewis Structures Worksheet! Be sure and get the updated worksheet. The last compound should be N2O3.
