X402, Test 1, Spring 2006. Answer key.
17 = A, 13 = B, 8 = C, 4 = D. My experience with classes such as this suggests that 80% = A,
60% = B, etc, are good cutoffs for the kind of tests I give. (Scores very near those cutoffs are
given a + or -. For example, the range 13-16.5 includes all B, from B- to B+.)
I am not showing the class statistics; that seems appropriate for a small class, but I am happy
to discuss the issue.
For each question, the circled number is your total points for that question. (Points for parts
may be shown, and are then added together to get the circled total for the question.) Check the
Be sure to read the comments on the test, regardless of scoring. It is often appropriate to
comment on certain features of your answer even if I do not take off points. Learn from the
I encourage you to go back and read the “Test follow-up” section of the “Sample test”
handout, especially if you are not happy with how you have done so far. Happy to discuss.
Remember, you are the judge of how you are doing relative to your background, needs, and
The chair template provided on the test is from ISIS/Draw. My non-Word structures shown in
class materials are drawn either with that program or with ChemSketch. See my web page for
an introduction to these chem drawing programs. (I have them installed on the classroom
computer, and can give brief demos.)
A brief, partial answer key follows. I have skimped on drawing structures. (You can ask me
about any of these, in class or privately.) Alternative answers are possible in some cases.
. Take home test, handed out class 7 (3/20), due next class (3/27). Test 2
should cover Ch 5 through 9; we will decide for sure at the end of class 6. (But
note that it will also review the earlier Ch, simply because the material is
inherently cumulative. It’s quite worthwhile to work on any major issues that
bothered you from those earlier chapters.) Test date is firm, even if chapter
coverage slips. Test 2 will be similar in style and length to Test 1. However,
former students would point out that reactions play an increasingly important
role as we go on (and are probably more complex than the few so far).
Think about the note sheet. Did it help you during the test? How might it have
