Recent Tutoring Session Reviews
"For today's session we focused heavily on Diels-Alder reactions and their stereochemistry. Near the end I also introduced the differences between Sn1 and Sn2 reactions for next week's session. The student was having issues with a few things: determining how the diene and dienophile connect via the mechanism, keeping track of the substituents, and determining whether the substituents resulted facing up or down (stereochemistry). I addressed this by coming up with a method of approaching these types of problems where we numbered the core carbons and then their substituents to make sure no carbons get lost in the process. I also explained the stereochemistry issue with a "C" analogy that made sense to her. While she did struggle at first, she is making progress, especially after we came up with that step-wise method for her. I asked that she continue working on Diels-Alder problems on her own to solidify what we went over."
"We did a review of Grignard and Cuprate rxns, comparison between the two and when the products differ, all about alcohol oxidation, went over the mechanism and differences (types or solvent and types of alcohols), went over the Wittig reaction mechanism."
"The student and I reviewed the concepts behind cyclohexane, equatorial and axial substituents, and orbital diagrams."
"We mostly covered the concept of ARIO and how it helps qualify acidity in an organic molecule. I spoke to the student mainly about what ARIO is, and tried to illustrate the concepts with some examples. She seemed really intent and dedicated to learning the material, and she recalled bits and pieces of the material as I went on. She had a great attitude and showed a willingness to learn."
"Today we reviewed the student's organic chemistry test. The student understood the material better after we reviewed the material."
"We did free radical reactions, mechanism, boiling and melting points of hydrocarbons, Hammond's postulate, and Gibbs Free energy based concepts."
"We covered organic nomenclature. In organic chemistry classes, nomenclature is oftentimes addressed only briefly."
"We reviewed some carbonyl mechanisms with a brief introduction to synthesis design. We also discussed leaving groups and oxidation states. Next time we will cover specific problems to more closely target test material."
"We covered halogenation, functional groups, Sn1, Sn2, E1, and E2 types of reactions. The student's attitude towards the material was very positive. She asked a lot of questions and that made best of the session. I recommend that she review the material much earlier before the exam date. There was a lot of material to be covered before her exam. Although we covered the majority of it, letting the material sink in over time so she can recall it for the finals would be more beneficial."
"Went over the student's exam. Corrected and discussed all mistakes on the exam. Started looking at acid/bases."
"Practiced more MS and IR identification of compounds and fragmentation. The student has definitely improved."
"We discussed naming and drawing of cycloalkanes. We also discussed the stability of different cyclohexane conformers and calculated the A-1,3 diaxial interactions that affect the stability of different isomers. I included in the session a variety of practice questions regarding drawing different isomers of cycloalkanes based on the student's performance. We went through most of the practice questions and the end chapter problem set as assigned by his professor. There was a significant improvement by the end of session. The student was able to name and draw cycloalkane conformers confidently."
