The Start of Aldehydes and Ketones

We started Chapter 19 on Friday. A lot of what we talked about was review (how to make C=O from alcohols, how to add nucleophiles/electrophiles to a C=O bond, etc.). The major points to remember all came at the end: when adding nucleophiles to the C=O, it is easier to activate either the electrophile (the C=O) by protonation OR the nucleophile by deprotonation. This is a theme that we will see again and again, so it is worth your time right now to make sure that you have a good handle on the concept.

Problem set 4 and its key have been posted; links to the right in the normal space.
