There could be two winners. If the first correct answer isn't from an undergraduate student then I'll select a second winner from those undergraduates who post the correct answer. You will need to identify yourself as an undergraduate in order to win. (Put "undergraduate" at the bottom of your comment.) Every undergraduate who posts a correct answer will have their names entered in a Christmas draw. The winner gets a free autographed copy of my book! (One entry per week. If you post a correct answer every week you will have ten chances to win.)
Some past winners are from distant lands so their chances of taking up my offer of a free lunch are slim. (That's why I can afford to do this!)
Name the molecules shown in the figure. Remember that your names have to be unambiguous. The best way to do this is to use the full IUPAC name but usually there are traditional names that will do. In this case there are trivial names for all of the molecules but make sure you have the stereochemistry correct.
New Rule: In order to win you must post your correct name. Anonymous and pseudoanonymous commenters can't win the free lunch.
UPDATE: Oh, oh. There's only one correct answer—congratulations Jason Oakley. I posted another answer that's almost correct (should be L-sorbose). All the rest of you need to review your understanding of Fischer projections. Here's a hint: Name This Molecule #1.
