IMPORTANT: In trying to help by summarizing a list of reaction types for which you will need to know the mechanisms of, I seemed to have caused confusion. This is a list of reaction TYPES for which you will need to now how to write the mechanisms, this is NOT a list of the reactions you need to know. You need to know ALL of the reactions we have studied, meaning you know how to give the products of those reactions, or, given the products, you know the reagents/conditions required to give those products.

The first review session for midterm #1 will be Friday, Feb 8th, 3:30-5:00PM, in PS F-101. The second review session will be Saturday Feb 9th, also 3:30PM - 5:00PM, also in PS F-101. The topics will be different for the 2 sessions. Both will be recorded and the recordings will be posted on the class website.
Material for the first midterm: This class is heading towards building your understanding of organic chemical reactions such that you know how they work well enough that yo can understand a reaction that you have never seen before, We are not there yet! In the mean time is is reasonable that you would want to now what kind of mechanism problem you might be expected to solve. For a summary of reaction TYPES that summarize the kinds of mechanism problem you might encounter on an exam, Click HERE. You will NOT be asked to draw the mechanism of any of the exact reactions included in this summary, the summary tells you of the TYPE of reaction mechanism you might see, but you could see this mechanism in many different contexts, including some that are harder than on this summary. As usual, check the practice and old exams for example actual mechanism problems.
FINDING IT DIFFICULT TO LEARN ALL OF THE REAGENTS?
1. Solve as many homework problems with a list or lists of the reactions spread out in front of you so that you don't continually get stuck, you really need to do as many homework problems as possible, and getting stuck is very bad.
2. Use the reaction lists to help you solve the homework problem, if you still can't do it, don't be afraid to look at the answer, this is part of learning JUST SO LONG AS YOU PROPERLY RECORD THAT YOU NEED TO GO BACK AND TRY THAT PROBLEM AGAIN (i.e. either the system records incorrect for you, or you hit the button that says "I need more practice", or you "star" the problem).
3. When doing the homework you should be writing as much as possible on paper as you work, for example, don't just enter the reagents in the reagents box in the question screen, write them out on paper before you do that, and ESPECIALLY, write them out on paper again if you get the problem wrong.
4. In the process of doing this you will find that you are learning at least the more common and simple ones (think about NBS/light, everybody knows that one!), but some of the more tricky ones with non-obvious reagents you will still struggle with, don't be afraid of that, you should expect that.
5. THEN, go to the lists of reactions and COVER UP the reagents and see how many you get correct, if correct then you are done with that reaction, make it so, if incorrect then you are not done, mark it incorrect, for most people some will be correct and some will be incorrect. Try to go through only the incorrect ones again and try to "get" them, but don't make any reaction correct unless you are SURE about it.
6. Then go back to the problems and repeat the cycle until a few hours before the exam, then power memorize the remaining incorrect ones!
Material for the first midterm: The first midterm will cover everything from elimination reaction to the end of the Alcohols section of the notes, there will be no organometals on the exam. The organometals problems in the practice exams on the homework site have been switched to "non-credit" questions, do not do those problems. There are NO ELIMINATION questions on the practice exams, but MAKE SURE that you know how to solve elimination problems of the kind given on the homework site!
There will be two pre-test review sessions. The first will be Friday, the exact time and location to be announced. The second will be Saturday, 3PM - 5PM, location to be announced. The topics will be different for the 2 sessions. Both will be recorded and the recordings will be posted on the class website.
My completed versions of the Alkynes and the Alcohols notes have been loaded on the lecture notes page. You can use these to make sure that your notes have no errors or gaps. More...

OFFICE HOURS this Semester: I usually have office hours 1-2PM on Mondays, However, this semester I have another commitment at that time, and so Monday office hours are 8:30AM - 9:30AM. Now, I just realized that I forgot to update the syllabus to reflect this (I have updated the version of the syllabus on this website). So please correct you copy of the syllabus to reflect these different Monday office hours times, thanks! More...

Quiz #1, a syllabus quiz, must be submitted by the end of the day tomorrow, Tuesday Jan 15th, after that, ALL quizzes will be due at 6PM each SUNDAY. I will post Quiz #2, which will be a chemistry quiz on Wednesday.
To see Quiz #1, Click HERE.
Quiz #1 must be submitted by the end of the day TUESDAY January 15th (i.e. before 11:59PM). The quiz submission tab at the top of this page will not be functional until Monday January 14th, i.e. after the drop/add deadline, and it will not open until around the middle of the day, I will post an announcement here. And so you should do the quiz and then be prepared to submit it next Tuesday but do NOT try to submit it before next Tuesday since the roster will not be loaded.
The second lecture has been posted on the recorded lectures page. I will not be announcing this on the main class web page fro each lecture from now on, please just go straight to the Recorded Lectures page, thanks! More...

This second semester class will start in an unusual way for me. Last semester we got quite a bit behind and we didn't finish the substitutions/eliminations section of the notes, we covered substitutions but not eliminations. Therefore, before we start the normal material for CHM 234, we need to finish off the eliminations section of the notes from CHM 233. Those students who took my CHM 233 class last semester, you will use the CHM 233 gapped notes you have for this, please BRING THEM TO CLASS on Monday Jan 7th! On the first day of class we will do a very quick review of substitutions and then get into the gapped elimination notes you already have.
The students who were NOT in my fall CHM 233 class will NEED A COPY of the gapped notes for elimination, to get a copy of these, Click HERE.
For the rest of the semester, ALL students will need a copy of the CHM 234 gapped notes, these are now available for purchase at the ASU bookstore.
For a copy of the course syllabus, Click HERE.
I will bring hard copies of the Elimination Reaction gapped notes and also the syllabus to class tomorrow, 7:30AM January 7th, but it will be more convenient for you if you can bring your own copies.
The class has a Facebook group page. I understand that not everybody likes to use Facebook, but this group has been quite successful in the past, Facebook allows very easy access, and when I ask the class if we should move away from Facebook the answer is always no. And so I encourage you join and to ask questions there, since everybody gets to see the answers, which therefore makes the questions useful to the entire class. Click HERE to access the group.
The syllabus is the same for both the regular/onground and the hybrid classes. To get a copy of the syllabus and class schedule, click HERE.
This class uses "gapped notes". You MUST buy a copy of these from the bookstore, they take the place of a textbook, which is not required for this class. The notes for the first few lectures are NOT part of the gapped notes package, to get a copy of these, Click HERE, or, if you were in my Fall 2018 CHM 233 class, you can use your CHM 233 gapped notes.
This class does NOT use a textbook. Textbooks are good for reference, but I strongly believe that they are not very good for teaching and learning. Your lecture notes should give you all of the information you need, and you can only learn organic chemistry by doing organic chemistry, not by reading it in a textbook. This class places a lot of emphasis the homework site, this is where you do organic chemistry and this is where you learn organic chemistry.
You do, however, need a copy of the Gapped Notes, see above.
Welcome to a new semester! The first class is Monday, Jan 7th. I will distribute hard copies of the syllabus and a small version of the gapped notes that should last the first few lectures.
I will not go over the syllabus/policies in class on Monday, most of you will know these from the first semester class.
Instead I made a video introduction to the class, click HERE

I look forward to working with you all this semester!
