NOTE: There are two kinds of spectrum solving problems on the homework site, ones that start with a mass spectrum and ones that start with a molecular formula. The former are harder to solve than the latter. I will not ask you to solve a spectrum problem starting with a mass spectrum on an exam, I will give you the molecular formula. I may ask you to solve a problem starting with a mass spectrum on a quiz, but not an exam. For that reason you should probably spend a lot less time, if any, on those problems that start with a mass spectrum.

The second midterm is to tomorrow. You are allowed to bring a model kit to the exam to solve conformation problems if it is helpful, HOWEVER, if you do, do NOT bring the entire kit and expect to build a model in the actual exam! You won't have time to do that and you will spill bonds and atoms all over the floor. Instead, bring a PRE-BULT cyclohexane and/or ethane, with some other atoms that can take the pace of the various substituents (don't try to build an isopropyl substituent, use a blue atom in it's place, etc.).

As already posted, the exam will include IR spectroscopy but no NMR.

DO NOT SIT ON THE FRONT ROW IN EITHER EXAM ROOM. The front row should be reserved for those students who arrive late so that they don't have to climb over students who have already started to work in order to find a seat.

There will be NO NMR AND NO MASS SPECTROMETRY on the test. IR Spectroscopy is DEFINITELY on the test!

Do NOT sit on the front row in either room. the front row is reserved for late comers so that they don't have to climb all over you who arrived on time to find a seat.

The projector in LS A-191 failed before lecture today, and so I had to use the whiteboard in class and re-record todays lecture in my office. As often happens when I do a lecture in my office I recorded it in a lot less time that I usually take in the classroom, especially because working on the whiteboard is slow. This is why the recorded lecture is somewhat short this time.  More...

We are starting to look at aspects of molecular structure that are 3-dimensional, and are therefore a bit harder to understand, especially pi-bonding. The best way to visualize these things is to make a model, either mechanically or in a computer, as shown in the following small videos (click the titles in bold below).
Pi-Bonds and Anti-Bonds
Visualizing the sigma- and pi-bonds in ethylene using the HGS model kit
Pi-Orbitals in Triple Bonds

Here are some more very small videos that attempt to illustrate some of the 3-D aspects of molecular structure that we have discussed in class recently.
Tetrahedral Geometry
Trigonal Planar Geometry
Linear Geometry
Rotation and Single Bonds

HOW QUIZZES WORK IN THIS CLASS:
Quizzes will be posted here, on THIS PAGE as pdf files. You download the pdf file, work out your answers to the questions, and when the Submit Quiz link opens, you enter your answers, A, B, C or D, to each question. You are allowed to submit answers to the quizzes as many times as you like before the deadline, only the last submission counts. The answer key is posted on this page, as a pdf file, after the deadline.

The FIRST QUIZ is due at 11:59PM this FRIDAY, AUGUST 25th. The first quiz will be a syllabus quiz. After that, ALL subsequent quizzes will be due on Sundays at 6PM. The second quiz of the semester will be due THIS Sunday, 6PM, August 27th. Quiz #2 will be a chemistry quiz.

To see Quiz #1, Click HERE. Do not try to submit Quiz #1 until the Submit Quiz link opens, which will probably be towards the end of the day Thursday August 24th. When the quiz submit link opens there will be an announcement on this page. Remember, late quizzes are NOT accepted, if you have technical or any other problems, this is what the dropped quizzes are for.

To get a copy of the syllabus for this class, 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. If you need a "starter" copy of the notes for the first lecture or two, you can click HERE to download them. This short set will only last 1 - 2 lectures, after that you will need your own copy of the complete set.

Gapped notes from a previous semester WILL NOT WORK, since I tend to change them at least a little bit every semester.

This class does NOT use a textbook. This does not mean that you cannot use a textbook, by all means get one if you would like a reference book. A good book is Organic Chemistry by Paula Bruice, however, just about all of the organic chemistry textbooks are the same. Used older editions of textbooks are a just as good as the most recent editions and are available for just a few dollars on Amazon. It should be easy for you to find the appropriate reading and problems that relate to the material that we are covering in any textbook, although some textbooks do not cover pericyclic reactions, a second semester topic (the Bruice one does).

Many students will ask me if they should get the textbook. Unfortunately I am not able to give a satisfactory answer, since different students have very different needs. Some students really need to study from a textbook and appreciate learning a topic from a different perspective. Some students want a permanent textbook to study for the MCAT, for example. You have to make your own decision on this I am afraid. However, as mentioned above, I have found that most students in my classes tend not use the textbook.

This course does NOT USE A CLICKER, and you do NOT NEED the 2 additional books that are recommended by the bookstore.

Note that the lab is a separate course, check your lab course website for requirements for that course.

A Molecular Model Kit, IS REQUIRED for CHM 233. The best kits are the HGS 1013Alpha kit and the HGS 1003Alpha kit. The HGS 1013Alpha kit is available at the ASU bookstore. It is also available on Amazon. The cheapest place to buy the 1013Alpha kit is direct from the manufacturer, followed by Amazon, the bookstore is the most convenient but most expensive.

Do not buy ANY OTHER MODEL KIT, in particular, the Prentice Hall Molecular Model Set For Organic Chemistry (or other kits like it), they make pretty models but is terrible for CHM 233.

It is not possible for me to give an override into this class since I am not allowed to override the reserved seat assignments or the room capacity. If you really want to get into this class, come during the first week and be persistent in trying to register online. There will be a lot of drop/add activity during the first week, persistence usually pays off. Remember that the class is offered both in the regular onground lecture format and also as an online/hybrid version. Both classes are basically identical. If you are registered for the online/hybrid class you are welcome to attend lecture with the regular class.
