Problem Set for Friday, 9-12-08(html) or (PDF) or (WORD)

Functional Group Table

An organic chemistry course is supposed to have a lot of memorizing.  We try to keep this to a minimum, but the minimum isn't nothing. For the first hour exam you will be responsible for memorizing the names of 17 "functional groups" and how to recognize and draw simple "constitutional" structures for them.  These functional groups are identified in red in a table that includes 16 additional functional groups that we'll probably encounter this semester.  You can access the table in three formats:  as a web page ; as a pdf file ; as an downloadable Excel Spreadsheet.  I find that sorting a spreadsheet different ways and stepping through it is an effective tool for memorization (that's how I learn your names).  Good luck.

(Clairvoyant "Science" ; Powers of 105 ;  Measuring the very small - Franklin; Feeling atoms SPM)

The first subject of the course is how we know about the existence of atoms, molecules, and bonds. It also teaches about the role of authority in science. To begin we will contrast two erroneous treatments of atomic and molecular structure a century ago. One of them is by two great scientists G. N. Lewis (Lewis dot structures) and J. J. Thomson (discoverer of the electron). The other is by "clairvoyant" frauds.

Erwin Meets Goldilocks (problem set due Monday, Sept. 22 - PDF document)

It's a pretty safe bet that you have never worked on this kind of problem before, so you should get started as soon as possible. Although you should learn how to solve all of the problems in this important problem set, it is unrealistic to solve them all by yourself. You should form groups, parcel out the problems, and explain what you learn to one another. 

Filip will demonstrate the use of Erwin Meets Goldilocks at the Thursday discussion section.  This program will help you develop a quantum mechanical intuition. You will be doing the relevant problem set in self-selected groups. Be sure that at least one representative from your group (or someone else who is willing to help you) attends the demonstration session. Bring your laptop to the session.  It would help if you download the Applet ahead of time.

Review Session:  8-10 pm Wednesday, Sept. 24, 116 WLH

There will be other review sessions on Thursday 7-10, 116 WLH (Filip and Peer Tutors)

You will have a full hour to write Friday's exam.  You may start at 10:30 and end at 11:30 in the normal lecture room (160 SCL)
or if it's important to get somewhere else by 11:30, you may choose the early option: start at 10:15 and end at 11:15.  
For the "early option" come to Room 111 SCL (at the other end of the hall from 160).

You may be wondering what kind of questions might appear on exams in this course. (Our first exam will occur on Friday, Sept. 26 The following PDF file contains a number of questions based on topics we have been discussing. These would be fair game. It might be useful to look them over as we go along.

The first exam papers will be returned in class on Monday, 9/29.

The class average was very good (80.0) with 1/3 of the scores greater than 85 and 2/3 of the scores greater than 76.  Congratulations, you seem to be learning a lot!

You can check your own points, both by question and total, using Post'em on ClassesV2.  If you have questions about the grading, consult the answer key (above) first, and then speak to  the grader of the relevant question (1-5, Schley; 6-8, McBride; 9-11, Kolundzic).

The "letter grades" posted there are of course almost insignificant, because they represent such a small, preliminary portion of the grading for the semester. But the course content is cumulative, so it can be helpful to see where you stand thus far, and whether it is important to be sure you're not falling behind.

  There is plenty of help available from the teaching staff.  5/6 of the semester scoring is still to come, so it's way too early either to despair or to become self-satisfied.  The plot to the right from year before last shows that the first exam score was not a great predictor of semester total. There is some correlation, but it is easy by working (or not) to move up (or down) by a letter grade.		exam correlation

To accommodate students who must leave for classes beginning at 11:35 (or who just wish to get it over with), the exam may be taken early from 10:15-11:15 in SCL 111 (southeast corner of SCL - at other end of the hall from 160).

Third Exam is coming up on Friday, Nov 14

 Dr. McBride will lead a review session on Wednesday evening
9-11 PM Room 211 Mason Lab

As usual, questions will focus on material covered since the previous exam (plus topics 364 and 365 of Lecture 29),
but it is assumed that you know the material covered earlier in the course.
Remember that Lecture 19 (October 17) will also be fair game on this exam,
but the exam will NOT include most of the material from Lecture 29
(Wednesday, November 12), which will be left for the semester final exam.

Old Third Exams for Practice :
Note - we are ahead of the pace for several previous years and very slightly ahead of last year,
so different material covered in some of the earlier exams will be relevant this year.

The exam will be budgeted for 150 minutes, but you will have 180 minutes to complete it. Roughly half of the questions will be focussed on material since the third hour exam. (If half of the final covers the last quarter of the course, and the final counts for half of the semester points, the last quarter of the course counts for 1/4 of the semester total.)
