DOs and DON'Ts for the midterm: | ||
Nov 15, 2004 | Thanks to the student who spotted the mistake in the acids and bases problem set: the very first entry in 1a should be Cl3CCO2H - in the problem set I missed out the carbon to which the three Cl atoms are attached, oops! | ||
Nov 15, 2004 | Lecture 19 Assignments: Reading 8.1-8.6 Problems 8.1-8.3, 8.9-8.13 | ||
Nov 12, 2004 | So, for those of you interested, there are about 313 people actively participating in the class (i.e., taking exams, as far as I can tell), and we had about 200 people in class today. That's about a two-thirds attendance, which is on the low side. From the list of names given, the average points total for students attending class is TEN POINTS HIGHER than for those not attending class - out of a total of 160 points so far... draw your own conclusions. Of the 25 students with the highest scores in the class, 20 of them were in class today. Of the 25 students with the lowest scores in the class (those who, as far as I can tell, have not dropped), 10 of them were in class today. | ||
Nov 12, 2004 | A "How-To" Guide for Quiz 2 is posted below, explaining how to answer the questions... | ||
Nov 12, 2004 | The more observant amongst you will have noticed that the notes for Lecture 17 were missing a page, a complete set are now posted! | ||
Nov 12, 2004 | Lecture 18 Assignments: Reading 10.7-10.9, 8.1-8.2 Problems 10.4, 10.16, 10.17, 10.21-10.23 | ||
Nov 10, 2004 | Quiz 2 is graded, the average was 12/30 (40%) and the high score was 29/30, the low was zero. Answer key is posted. | ||
Nov 10, 2004 | Lecture 17 Assignments: Reading 6.6-6.7, 10.9 Problems 10.5 | ||
Nov 08, 2004 | Thanks to the student who pointed out that I can't count carbons! On the carbocation rearrangement handout, the bottom ring expansion example was incorrect (there was a H atom where there should have been a methyl group). A correct version is now posted... although, thinking about it, once the ring expansion has occurred, the secondary carbocation would probably undergo a 1,2-hydride shift to form a tertiary (and therefore more stable) carbocation, resulting in the X group ending up on the same ring-carbon as the methyl group... oops. Well, hopefully you managed to follow that! | ||
Nov 08, 2004 | Lecture 16 Assignments: Reading Ch 6 Problems 6.13, 6.37-6.49 | ||
Nov 07, 2004 | New problem sets and mechanism guides are posted below | ||
Nov 05, 2004 | I plan to post some more Problem Sets over the weekend, and perhaps some mechanism guides if I get the chance... | ||

Nov 05, 2004 | Lecture 15 Assignments: Reading Ch 6.3-6.7 Problems 6.9-6.11, 6.17-6.38 | ||
Nov 03, 2004 | A note from Adam: why (as drawn) is the nitrogen atom in methyl isocyanate Me-N=C=O sp2 hybridized and not sp? Well, it has three things around it, two atoms and one lone pair, and so will hybridize to form 3 sp2 orbitals, and one p orbital will remain unhybridized. The lone pair gets placed in one of the lower energy sp2 hybrid orbitals. In the case of a carbocation, there are no electrons in the unhybridized p-orbital, so it does not need to hybridize to lower the energy of the system... (hopefully this will make sense to the people Adam confused earlier today!!) | ||

Oct 27, 2004 | Grading is done... finally, so now we get to go home... (mean was 52%, low 13%, high 98%) - well done. Blank exam and answer key are posted above. | ||
Oct 26, 2004 | Thanks to the people in office hours for pointing out mistakes on the stereochemistry problem set answer key: page 8, 8b, the bottom stereocenter should be R, not S, and vice-versa in the enantiomer; page 9, 9j, this is not the Z isomer, it cannot be determined, i.e., it is nether E nor Z. A new answer key is now posted... | ||
Oct 25, 2004 | Make sure you go to the correct room for the midterm: room assignments are based on the first letter of your last name: A-J in Bunche 1209B, K-Z in CS50 | ||

DOs and DON'Ts for the midterm: | ||
Oct 25, 2004 | Lecture 11 Assignments: err... I think there's a midterm on Wednesday - study for that! | ||
Oct 25, 2004 | Any office hours or discussion sections that are scheduled on Wednesday AFTER the midterm are cancelled | ||
Oct 24, 2004 | The answers to the conformational analysis and stereochemistry questions are now posted - see below | ||
Oct 24, 2004 | Midterm 1 will cover Chapters 1, 2, and 3 - now stop asking me this question! | ||
Oct 22, 2004 | Lecture 10 Assignments: Reading Review Ch 3, Problems 3.6-3.9, 3.24-3.36 | ||
Oct 22, 2004 | Spotted a mistake in my lecture notes from Wednesday - at the bottom of page 7 (the second example in assigning priorities to groups, I mixed up which group was 3 and which was 4. The corrected pdf file has been uploaded to the lecture notes page. Also, I'm not sure if I got it wrong in class, but I'll be going over it again today... | ||
Oct 21, 2004 | ...and on that note, YES, you can use your model kits for the exams in this class, but they MUST be brought in completely UNASSEMBLED | ||
Oct 21, 2004 | Thanks to some sleuthing by Cari, she has found a model kit on Amazon, it's expensive, but cheaper than most textbooks after all, and you could probably re-sell it in the future... | ||
Oct 20, 2004 | Lecture 9 Assignments: Reading 2.9-3.4, Problems 2.16, 2.46-2.61, 3.1-3.5, 3.10-3.23 (I didn't cover enough in class today for you to be able to do all of these problems yet, so don't stress...) | ||
Oct 19, 2004 | Room assignments for the midterm next Wednesday (Oct 27th) are based on the first letter of your last name: A-J in Bunche 1209B, K-Z in CS50 | ||
Oct 18, 2004 | Lecture 8 Assignments: Reading Review Chapter 2, Problems 2.10-2.15, 2.31-2.45 | ||

Oct 14, 2004 | If you have trouble opening any of the pdf files on this site (like someone I know does...), make sure you have the latest version of Acrobat Reader. If you still have problems, it may be your browser, so just right-click, download the whole file to your computer and everything should be OK. Let me know of any more problems... | ||
Oct 14, 2004 | Please do not ask me if you can take the Final earlier in Finals week. The answer is NO, will remain NO, and has always been NO. Believe me, it would make my life easier too if it was earlier in the week, but I have no control over these things. Sorry... | ||
Oct 14, 2004 | The quiz 1 mean was an incredibly high 26/30, with over 30 people getting the maximum score of 35 points. Well Done! | ||
Oct 14, 2004 | Lecture 6 Assignments: Reading Ch 2-2.6, Problems 2.9, 2.27, 2.28 | ||
Oct 13, 2004 | A few mistakes to point out in the notes/problem sets (I am human...): In the problem set on resonance, the third resonance contributor in the answer key for 10a (page 9) is missing a methyl group, and at the end of lecture 5, I got propanol wrong! I drew it with two carbons instead of three. The necessary pdf files have been replaced and are now correct. If you spot mistakes in my handouts or lecture notes, PLEASE LET ME KNOW. | ||
Oct 12, 2004 | The quiz tomorrow will NOT be multiple choice... but it will be short and fairly straightforward. GOOD LUCK! | ||
Oct 11, 2004 | Lecture 5 Assignments: Reading Browse through Ch 2, Problems 2.1, 2.2, 2.8, 2.17-2.21, 2.24-2.26... and study for the quiz on Wednesday! | ||

Oct 08, 2004 | Answers to all problem sets thus far will either be posted later today, or on Sunday at the latest... | ||
Oct 08, 2004 | Lecture 4 Assignments: Reading Browse through Ch 2, Problems 1.18, 1.55-1.70 | ||
Oct 07, 2004 | Decided to start scanning and posting my own lecture notes - they are not necessarily a replacement for the ASUCLA ones, but hopefully you will find them helpful. The link is here and also near the top of the main 30A page | ||
Oct 06, 2004 | ***Due to unforseen circumstances, Adam had to cancel his discussion section this afternoon (1G) at the last minute - sorry for the inconvenience. No one will be graded down or lose points for this section not happening - if you are confident in the material so far, just pick up discussions next week, but feel free to sit in on ANY other discussion this week to catch-up if you wish*** | ||
Oct 06, 2004 | Lecture 3 Assignments: Reading ALL Ch 1, Problems 1.15-1.17, 1.50-1.54 | ||
Oct 05, 2004 | I will not specifically lecture on sections 1.3 (Functional Groups) and 1.5 (Polar and Nonpolar Molecules), so work through these sections on your own, and if you have any questions, ask me or your TA - the material is pretty straightforward | ||
Oct 05, 2004 | Lecture 1 Assignments: Reading 1-1.4, Problems 1.1-1.5, 1.19-1.22 | ||
