Recent Tutoring Session Reviews
"Today, the student I went over her NMR PowerPoint from her Orgo class that her professor is going over with the class. They have not finished the lecture as of yet, but we went over it together. We then went ahead and discussed problem-solving strategies as well as did two practice IR/NMR problems (one from the PowerPoint and one from the school chem website). During our next appointment, we will go over more IR/NMR problems from her textbook and from the website."
"We looked at reactions of alkenes/alkynes: acidic additions, cis/trans reductions on alkynes, ozonolysis, halogenation, elimination, substitution, and epoxidations. The student was having some difficulty with predicting product outcomes. She picked it up very fast and was able to do the problems more independently. We talked about what specifics to look out for on a problem by problem basis."
"We reviewed oxidation and the mechanisms, PCC vs. Jones reagents, keto-enol-diol equilibrium, double bond additions, drawing inductive effects, peroxy acids, epoxides, acid vs. base epoxide openings, stereospecificity of double bond additions, cis and trans diols from OsO4, and epoxides."
"We went over how to do SN2 reactions, how to break them down, what constitutes SN2 versus SN1, etc. The student was very optimistic and happy to be understanding the reactions by the end of the session. He has more homework problems to complete, and he will show me his worked out problems tomorrow. I will bring the worksheet for tomorrow's session."
"We went over reactions of alcohols, along with all the mechanisms involved. We then finished up with some NMR work on chemically equivalent, enantiotopic, diastereotopic, and homotopic protons and fluorines."
"We went over the student's homework assignment on nucleophilic substitution reactions, which included determining the reaction type (Sn1 or Sn2) by examining the nucleophile, the degree of halide, and the type of solvent used. We also went over the stepwise mechanisms for each reaction type. I suggested she practice the mechanisms for each so she can apply it to any structure she is given. I also suggested she make notecards of reagents to help remember what the products will be given certain conditions, and to review my practice sets for this section online."
