Recent Tutoring Session Reviews
"Today we did a Sn1 Sn2 and E1 review. We discussed what are the conditions for each, and when do these reactions compete. We also went over rating compounds in terms of their Sn1 and Sn2 reactivities. We then discussed why the benzylic position is so reactive, Sn1 and Sn2 examples, and oxidizing the benzylic carbon with KMnO4."
"We covered Diels Alder reaction. We went through the concept and the driving force for Diels Alder. The mechanism for this reaction was explained. The student was able to predict the correct mechanism and the products. In addition, the stereochemistry of the product was elaborated and a retro-Diels Alder reaction was explained."
"We covered Newman projections and chair orientations for cyclic compounds. This included how to draw them, how to interpret them, and the typical questions related to them. I walked the student through some example problems and gave him pointers as he approached some of the problems independently. We then spent a short time covering a little bit about nomenclature for organic molecules."
"We covered Newman projections, wedge and dash models, cyclopentane conformers, and some chemical nomenclature. The student picked up most of the concepts pretty quickly, and continued to do several problems independently and correctly. She struggled the most with overall visualizing of the 3-D projections, but she managed to pick it up quickly. She seemed to have some idea of it, but was confused as to how to approach the problems. Strategies used included mainly going through problems with her, and then allowing her to do problems independently. If she made any errors, I asked the questions to allow her to come to that conclusion herself. I did not leave her with extra practice. I saw her last test scores. Hopefully we can see improvement on her quiz on Monday."
"We covered Newman projections: how to draw them from wedge dash structures, how to judge the relative energies, how to generate the successive Newman projections generated from the first one, and how to draw the resulting energy diagram from the 6 different Newman projections. We then covered how to determine the hybridization of a given atom and how to designate the orbitals making up a given bond. We then began looking at nomenclature, specifically how to approach finding the longest chain and how to decide where to start numbering. We will continue this in our next session."
"We covered resonance, stability of conjugate bases and their corresponding acid strength, drawing Newman and Fischer projections, and the concepts of stereocenters, enantiomers, meso compounds, and racemic mixtures."
