A good day of chemistry today. The focus was on acid/base chemistry and we learned how to use pKa values to determine which way is the preferred direction in an acid/base reaction at equilibrium. To top it off, we then took that same acid/base reaction and showed how to draw arrows indicating electron movement that led to the transformations shown (in both directions). Using this method allowed us to think of acids as electron pair acceptors (instead of proton donors) and bases as electron pair donors (instead of proton acceptors). This Lewis acid/base definition is much more general and will serve us well over the course of the next 29 weeks of organic chemistry.
Two problem sets were posted and I showed how to subscribe to the chemistry podcasts.
Today's title is inspired by The Wizard of Oz, hence the picture.
BRING YOUR MODELS ON MONDAY!
