Now, perhaps some of you can make sense of the first problem there, but I am not sure that I can. It's nucleophilic substitution reaction, but I can't for the life of me figure out the mechanism. And this is all that I have been working on for the past few days, and pretty much all I will do until Tuesday evening. i am not sure that I can pass this final either. All I know is that it is 10:30 on a Saturday night, and I am in the student union building with about 8 inches of paper and a meg of online notes. The exam is, of course, completely cumulative. So I would guess that I have well over a hundred mechanisms to memorize in detail along with various reactivities and reagents. I certainly don't remember the one for above. I finally got my car re-plated and insured after an excruciatingly long hiatus. I miss driving, but I certainly don't miss any of the bills associated with the operation of a vehicle. Every little thing adds up, and even the little things for an automobile wind up costing and arm and a leg. I don't have any kind of shop up here, so anything big (or anything at all) needs to be done by a mechanic. Now I all I have left is to psych myself up for a drive across the Prairies in December. I think I am going to pick up an XM radio and an audiobook copy of Crime and Punishment or the Brothers Karemazov. I figure while in the pursuit of epic feats... The last time I drove across the country was a few years ago now, crazy as it seems. Past due for another trip, I think. I am going to be seriously cutting back on the amount of time that i spend in class as of next semester, and likely cutting down to just one job, and so I hope to be on here a little more often. I am sad to say that when things get a little hectic, it's usually the side projects that get cut first.
