This is a stunning link to a video showing how sample preparations, natural product solvent extractions and precipitation of insoluble organic salts by reaction with mineral acids is accomplished in the real world. Just like in our lab, huh? Makes one wonder what their Health and Safety Committee thinks of their procedures.
Really though, as an organic chemistry student you can chemically make sense of everything that they are doing in this video.

CH 2113 Class Assignment
So, who would like to know what was on the final exam?
This assignment has a number of parts. First you need to go over the end of chapter questions from the textbook (Chap. 2 - Chap. 8) and select one question from each chapter that you think is a good question. A good question would be one where the answer is not trivial, it requires thought to answer and covers at least one important principle taught in the chapter. The question may be from the syllabus set but may be any other end of chapter question.
Then log onto the comments section of this blog and state your selection. Your comment should include a statement of the chapter and question and a short reason why you think it would be a good exam question. Then read the other students comments as they come in and re-post if you change your mind.
Ultimately the class should agree on one question from each chapter that meets the criteria. At least two questions should be on synthesis.
Your mark on the assignment will be out of 20 and 10/20 will be my assessment of how well the final set of questions meets the criteria (all students that participate will get the same mark). The remaining 10/20 will be a participation mark assessed by the nature and quality of your own contributions to the discussion.
The payoff? I will select one of the seven questions from your list for the first question on the final exam and it will have a value of 10%. I reserve the right to make minor changes to the question but you will be able to recognize it.
The deadline for the final class list of questions will be midnight, Sunday, December 3. All students must make a contribution to the discussion by Sunday, November 26.

Sad Days for Honeydew
It would appear that the usefulness of a blog in teaching has its limits and they are low. I have been looking around to see what other faculty are doing with their blogs and the time - effort - benefit equation does not seem favourable.
That said, there have been some recent news articles written about professor Honeydew and I might note that they are rather sad and disturbing.

Sort of makes you wonder if the internet is a reliable source of information afterall.

Slightly Cracked Honeydew
So ... when I was in my late teens I lifted a snowmobile out of a ditch and felt something "give" in my back. I was young and fit and just shook off the pain. Recently however there are occasional trigger events where I lift something heavy or awkward and when my back "gives" I am in pain for a week and for at least half of that time I simply cannot walk or straighten my back. That is what happened this past week and I thank you all for your cooperation with Sebastien as he carried the load by himself.
