aahhhh i remember making those decisions. nice sounding name (like one your parents know) vs state school that is packed with power-house researchers (like uiuc).
I agree with your previous responder. Remember, a Ph.D. in Organic Chemistry is much more about the research and your adviser than anything.
My advice is to go to the place that has more people you could see yourself working with (for?). Chances are, within the first ~6 months your ideas about what you want to spend the next 5-6 years researching will change. Mine did. If there are 10 people at place A and 2 at place B. Go to A, no question.
The second level of analysis I would recommend is the facilities. In other words, in a tie, at which institution will you be able to do research faster and better? This takes a lot of digging and thinking on your part, but for a graduate student, the facilities available (NMR, MS, cell culture?, high-through-put screening, computational clusters?, software, ......it all depends...... could go on forever) strongly affect the level of experiments you can do.
In response to the previous response: the compliment to Denmark at Yale would be Scott Miller. He rocks.
good luck in your decision,
