Monday's Molecule #145
I'm restarting Monday's Molecule. The last one was almost two years ago [Monday's Molecule #144].
The rules have changed a bit. Monday's Molecule will no longer be linked to a Noble Prize because I'm running out of Nobel Prizes that lend themselves to such a linkage. All you have to do is supply the complete, unambiguous, name of the molecule to win a free lunch. Post your answer in the comments. I'll hold off releasing any comments for 24 hours. The first one with the correct answer wins.
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.)
Some past winners are from distant lands so their chances of taking up my offer of a free lunch are slim. Many of them have kindly donated their free lunch to the next contest.
Name the molecule shown in the figure. Remember that your name has to be unambiguous. The best way to do this is to use the full IUPAC name but there are several traditional names that will do.
