Default organic chemistry labs

Hi,
Does anyone know where I could find some organic chemistry labs, or ideas for labs designed for an organic chemistry course.
I'm thinking things along the lines of hop oil extraction and the chemistry behind it or different malt things like the production of dimethyl sulfide pre and post fermentation or even yeast things. Getting into biochemistry would also be fine.
I'm a student who, due to my senior project which was to start a beer "CSA," has missed all of the organic chemistry labs this term and now am scrambling to due lab write-ups on things relevant to my education and project.
Any ideas?
Thanks a lot.

You might want to check out the M.I.T. Open course ware, they have basic chemistry to physical chemistry. So I'm sure if you looked hard enough you would be able to find what you are looking for.

Wait. So you missed a month or two of O-Chem labs, and you school is letting you make them up by writing about beer? Huh.

Well, it's a little more intense than just, "writing about beer," but yes, I am allowed to do the same amount of work as everyone else at a different time to make up for work I missed. It's actually nice to study with people who are down to earth enough to realize that sometimes the curriculum isn't the only way to learn things and are willing to let motivated students pursue other paths that are more relevant to their education.

Yea I must say that would be nice, I'm a chem major and I'm 99% sure my prof's wouldn't let me go out on my own like that. I guess I could do some guided research in beer with one of the o-chem guys but I would rather spend my free time drinking the beer.

Since I never took organic chemistry I don't have any feel for what sorts of things go in the labs but one thing did come to mind: run through the oxidation states of ethanol i.e. add a bit of oxidizing agent to it noting production of acetaldehyde, easily detectable by smell. Add more oxidizing agent and note production of acetic acid - also easily detectable by smell. I suspect this may be too trivial but thought I'd throw it out anyway. Or if you want to stink up the place use butyl alcohol.

To do the same thing with more sophistication you could get one of those low level alcohol test kits that does the first oxidation with NAD in the presence of alcohol dehydrogenase and measures the NADH production by UV absorption and then catalyzes the second step with aldehyde dehydrogenase. Again the increase in NADH can be measured.

^^^ I'm sure he could use the mass spec in the lab :P
