Recent Tutoring Session Reviews
"Today, the student and I went over the three things in Organic Chemistry that his professor mentioned that he was struggling with. We discussed pKa, how to study reagents, SN1 vs. SN2 vs. E1 vs. E2, and practicing mechanisms using arrow drawing and electron pushing techniques. He showed that he can really pick up on things quickly and started to get a hang of the material that he was initially having difficulty with. We will schedule our next session for early next week to start going over newer material."
"We looked at reactions of alkenes: hydroboration; hydrogenation; halogenation; Sn1, Sn2, E1, and E2; cis-alkyne reduction; trans-alkyne reduction; some synthesis problems; and R/S configuration. She had a hard time identifying the part of the molecule in which chemistry was taking place. We went over mechanisms, and when she thought of it that way, the processes were clearer."
"We reviewed making cis and trans double bonds from alkynes, synthesis tips, and how to think about reactions. We went over lots of sample problems from a sample exam. We reviewed how to determine which elimination reaction produced which double bond, making epoxides and epoxide stereochemistry, ozonolysis, how to determine the final product from the pieces, O3/S(CH3)2 vs. KMnO4, heat and acid in oxidatively cleaving double bonds, electronegativity, and alkane, alkene, and alkyne pKas."
"We went over everything that will be on the student's exam tomorrow: Sn1/2, E1/2, Diels-Alder, reactivity trends, nucleophilicity trends, and addition reactions. The student did well with Sn2/Sn1 reactions and felt more confident in those areas. He is improving in his E1/2 reactivity knowledge and problem-solving ability. The student has almost all of his recommended book problems to do tonight for practice, and he will be making some notecards with study tips that he and I went over. I think, overall, he feels better about a lot of material."
"We went over ozonolysis and revisited anti-Markovnikov addition to alkenes, especially as it pertained to synthesis questions. We also went over the stereochemical outcomes that you get when you add either cis or trans groups to cis or trans alkenes."
"We went over the practice quiz, which was on the last chapter of the semester. It was on fatty acid oxidation as well as fatty acid synthesis. It involved determining the number of ATPs produced from such oxidation, as well as the basic mechanism of reduction using NADPH. Then, we went over a little HW. Also, the student did well on this past midterm by getting a score that was a little above the class average."
