Recent Tutoring Session Reviews
"This session focused on chapter 21 synthesis problems in preparation for the student's upcoming exam. He seems well-prepared and only needs to focus on memorizing the most recent reagents and how to best use them for synthesis purposes."
"We covered ketones, aldehydes, reductions, formation of hydrates, enamines, imines, and hemi acetals. We covered the use of acetals as a protecting group. We also discussed strategies for protecting alcohols using TBDMS groups. We discussed Wittig reactions. 1,4 versus 1,2, addition using cuprates, and Michael acceptors. I will send a list of acceptors and donors to the student. We will meet again after Spring Break. He seems to have a good understanding of the concepts."
"Review for quiz on enols, enolate ions, alkylation of enolate ions, alpha halogenation of ketones, haloform reaction, Hell-Volhard-Zelinsky reaction, aldol condensation of ketones and aldehydes, dehydration of aldol products. Crossed aldol-condensation will not be on this quiz so only worked on aldol condensations with another molecule of same aldehyde/ketone."
"We covered the rest of the organic chemistry practice exams. I was glad to see the student owning the reactions and being able to use his organic intuition to predict reactions. It takes a while to develop that, and I hope he can see it more and more as he continues taking the class. Soon he will be attending his professor's review session to check answers and compare explanations."
"We reviewed for her final exam that she will be taking tomorrow. We went over thermodynamic problems, PH problems and bonding. We went over her practice test to make sure we answered any specific question she had. She will continue to study for her exam."
"The student and I met today for 2 hours. We went over last-minute concepts and practice problems before her final exam tomorrow. She has been working hard this quarter and spending lots of time studying organic chemistry, so I'm sure she will do great tomorrow."
"We focused on NMR spectroscopy. We worked on using the information given from the spectra in order to deduce the correct structure of the molecule. We identified patterns to look for, as well as general guidelines to make the process easier."
"Today's session covered ketone and aldehyde mechanism, as well as concepts covered last week. Specifically, we went over a quiz that the student had taken the past week that she struggled with. I provided guidance with the mechanisms while she did the critical thinking in order to arrive at the correct answers. We then began covering a new topic of carboxylic acid derivatives, going over the nucleophilic acyl substitution and the concept of leaving groups. She was left to do the group work assigned by her teacher as a review of this new topic, and the next session will be utilized as a review session before her next cumulative exam. She seems to be improving in her methodology in approaching questions that ask her to provide step-by-step reactions within a mechanism."
"The student and I spent today's session going over her second test from the semester. While she had some good reasoning and logic to solve synthesis problems, she didn't have all of the necessary mechanisms and reactions memorized to solve synthesis problems. I helped her to reason through each question and we identified what information she was missing and filled in those gaps. I then instructed her to make flashcards of all the reactions in order to get on top of the material and begin to prepare for her final."
"We continued to go over NMR, which the student is getting quite good at figuring out by himself. I think he has basically reached proficiency in this skill, as it can be very difficult to predict the spectra perfectly accurately."
"The student did one and a half of her quizzes that she brought, which dealt with reactions. She understands the general concepts. I think she started to grasp more of the finer points today! We will meet up again Sunday and pick up where we left off."
"The student and I were able to spend a lot of time today working on synthesis problems involving aldehyde/ketone reactions and reduction reactions. A lot of times he feels as though he lacks the creativity to come up with the reagents himself, but I realized that when I time him and create some sort of pressure, he is able to figure a lot on his own. I am going to try this a couple more times and have a practice 'quiz' before his quiz on Thursday. He also was able to do a pretty challenging mechanism on his own and seems to be doing pretty well with mechanisms."
