Good
Prof. Nanette is pretty alright for lab. She’s a fair grader. Before lab, she explains everything so you’re not lost while doing experiments. For each lab, there are written reports, practical, and quiz at the end of the sem. You will really have to work for your grade. I would totally recommend taking her for lab. She curves heavily as well!

Poor
Prof. Wachter doesn't do much to alleviate the hardships of class, so you're basically on your own. Her lectures aren't well structured, so you have to heavily rely on the book if you want to understand things. However, she's pretty fair and she doesn't throw any curveballs on exams. Practice exams and in-class work are pretty helpful.

Blurring the lines between online and on-campus classrooms: Using Voicethread to foster collaborative learning in organic chemistry
ACS Symposium Series, Vol. 1261; American Chemical Scoiety: Washington, DC
Engaging students in organic chemistry is especially challenging for online courses. Voicethread is a cloud-based multimedia platform that allows users to edit content and interact via text or video comments. Hofstra University has been utilizing Voicethread to foster asynchronous collaborative learning within small groups of students in our online organic chemistry course. Results for individual learner scores on Voicethread Collaborative Learning Group assignments correlated positively with learners’ average exam scores.

Using NMR to investigate products of aldol reactions: Identifying aldol addition versus condensation products or conjugate addition products from crossed aldol reactions of aromatic aldehydes and ketones
ACS Symposium Series, Vol. 1128; American Chemical Scoiety: Washington, DC.
Crossed aldol condensation of benzaldehydes with acetophenone is typically part of an undergraduate organic laboratory curriculum. The experiment involves the reaction of the enolate of acetophenone with an aromatic aldehyde generating benzalacetophenone (chalcone). The initially formed β−hydroxyketone rapidly dehydrates to generate an α,β-unsaturated ketone, even under the basic conditions usually employed for the acyl addition reaction. Elimination is favored because of resonance stabilization of the fully conjugated product. However, in the reaction of 2′-hydroxyacetophenone with benzaldehyde, the partially saturated β−hydroxyketone intermediate initially formed can be isolated in moderate to good yield. In a similar experiment, when an excess of acetophenone is treated with 2-pyridine carboxaldehyde, the initially formed α,β-unsaturated ketone undergoes rapid Michael-addition with a second equivalent of the enolate to yield a symmetric diketone. The unanticipated products of both of these reactions contains diastereotopic methylene hydrogen atoms that are easily identifiable and well resolved in the 1H NMR spectrum. Moreover, a COSY experiment clearly demonstrates coupling between the methylene protons with one another and with the proton of the β-carbon. Each of these experiments highlights concepts taught in organic chemistry using techniques traditionally introduced in an introductory organic laboratory course.

Rapid screening and quantification of synthetic cannabinoids in herbal products with NMR spectroscopic methods
Analytical Methods; Royal Society of Chemistry
The abuse of “Spice” designer drugs, herbal incenses containing synthetic cannabinoids, has led to an increase in medical incidents and triggered legislations throughout the world banning these harmful designer substances. As more cannabinoids are added to that list, forensic analytical labs are experiencing sample backlogs due to the variety of the products and the addition of new and still-legal compounds. Here we use NMR spectroscopy exclusively to screen for and quantify synthetic cannabinoids in herbal products. In contrast to other qualitative and quantitative NMR methods that have appeared in the literature, in our methods synthetic cannabinoids were directly extracted with NMR solvent without any conventional lengthy isolation, purification or chromatographic separations. 1H NMR and proton correlation spectroscopy (COSY and TOCSY) were successfully employed to generate molecular fingerprints for synthetic cannabinoids in herbal extracts, taking advantage of the spectroscopic separation power from NMR spectroscopy. The added dimension from the 2D NMR techniques provided additional signals that are easier to differentiate than those acquired by 1D NMR analysis, and valuable correlation signals for screening and comparison. Quantification of cannabinoids by NMR was carried out in d6-acetone solutions with maleic acid as an internal standard, which generated quantitative results that were comparable to our previous HPLC quantification. The overall data suggest that in approximately one hour, NMR spectroscopy can be used exclusively for the non-destructive screening and quantification of synthetic drugs in complex herbal matrices.
