There WAS one pair of 3-D glasses missing at the end of the period on Friday and I was very upset. Fortunately, the person in possession of those glasses has called me and I will return your exams when I've finished grading them (and will NOT hold them hostage!).

The 7-membered ring is named: 1,6-dibromo-2-fluoro-1-isopropylcycloheptane. You must start numbering at the C with the 2 substituents. The 4-membered ring is named: 1-amino-1,3-diethylcyclobutane

Helpful Item: Did you know that you may bring molecular models with you to exams? Well, you can. You may even PRE-ASSEMBLE them. You may NOT, however, share them with anyone else during exams.

I've had only one person who emailed me the name of the rotating molecule on the 255 homepage. Are there no other "takers"? Hint: the atom in yellow is on the LEFT side of the dividing "steps" between metals and nonmetals on the periodic table. The DuPont-Marshall Lecture at the University of Pennsylvania this year will be given by George Olah. It will be on Tuesday, Oct. 21 at 5:00 pm in Room 102 in the Chemistry Building on the corner of 34th & Spruce Sts. George Olah, winner of a Nobel Prize in Chemistry, is at the Loker Hydrocarbon Research Institute of the University of Southern California, LA. Look up the work for which he won his Nobel Prize. When did he get it? Write to me with the answers.
