Recent Tutoring Session Reviews
"We looked at Sn1/E1 and Sn2/E2 reactions and how to understand when each are occurring. The student was having a hard time with the elimination reactions and where the double bond formed. She picked up the material very quickly and was able to do many example problems as we went forward. We spoke about what to look out for to distinguish the reaction pathway and pointed out specifics as we did problems."
"We reviewed specific problems, stereochemistry of electrophilic addition reaction, aromatic electrophilic substitution reactions, Friedel craft reactions and mechanisms, intramolecular AES, meso compounds, pKas, and nitrogen's lone pair basicity."
"We went over the student's slides so that I could explain what's going on. He's taking graduate-level Organic synthesis, and she is learning protecting groups. First, I had to explain that a protecting group hides a functional group in your molecule that would otherwise interfere or react with a reagent being used on another part of the molecule. Then, we began going over each type."
"We went through a practice exam focusing on NMR and MS spectroscopy. We discussed 1H NMR and 13C NMR and how to predict the number of signals in both 1H and 13c NMR. We also covered some mass spectrometry questions. We solved for the structure from given data and matched the signals with the structure."
"We worked through several problems involving Sn2, Sn1, E2, and E1 mechanisms. The student needed a bit of help walking through the problems to identify nucleophiles and electrophiles, push electrons along curly arrows, and the types of reactions. We discussed general principles for determining what makes a given reaction favorable and how to draw acid vs base catalyzed mechanisms."
"Chapter 4 concepts that we covered today were naming and Newman projections. He had difficulties with properly drawing chair conformations and knowing if the H were axial or equatorial. He has plenty of practice problems to do, and he showed excellent understanding of Newman projections."
