Recent Tutoring Session Reviews
"We worked on alcohol and ether synthesis including hydroboration and oxy-mercuration. We also covered crown ethers and their uses, epoxidation reaction and reagents. We worked on naming several ether containing compounds. Also discussed were mCPBA epoxidation mechanisms, halohydrin formation, and epoxide synthesis. We worked a synthesis problem to prepare a substituted phenol."
"The student and I worked on practice problems pertaining to ketones and aldehydes, discussing the more specific reaction mechanisms - including the Grignard reaction that converts a ketone into an alcohol. The reactivity and reaction mechanisms with imines and enamines, the Wittig reaction and the wolff-kishner reduction reaction involving hydrazine to convert a ketone into alkanes. The student is able to predict the product formed from the reaction but we are working on her understanding the actual mechanism and movement of electrons."
"This session, we focused on going through chapter 17 material on aldehyde and ketone reactions. I emphasized the conceptual similarities of these reactions with those of the carboxylic acid derivatives and we did some practice problems to reinforce these concepts. The student has a test coming up next Wednesday and I told her to study these materials up until her test."
"Test review for mid-term covering stereochemistry, radical halogenation, Sn1, and Sn2 reactions. Mechanism for radical halogenation, selectivity for different halogens at room temperature, loss of selectivity for radical halogenation at high temperatures. Factors that determine whether substitution will occur via Sn1 or Sn2, mechanisms for each."
"We covered a mass quantity of carboxylic acid and amid reactions in preparation for her exam tomorrow. Hoffman elimination, aldol condensation, diazonium rxns, and more. We spoke about study skills and exam preparation as well."
"The student and I finished covering the aldol/clause condensation reactions. We went over some more problems from the homework that he had to do. It is really encouraging to see that he can do most of the problems on his own now. He has definitely come a long way in figuring out how to approach a problem and write a mechanism flawlessly. He has been very thorough in his mechanisms. He also has been improving significantly in challenging orgo problems that involve ring structures. Tomorrow, we will finish studying for the quiz on Thursday."
"We covered the amine section of the organic chemistry coursework. We first went through some basics of the hybridization of orbitals and resonance structures. We went through several examples, and she was able to work through them after the review. In the next session, using the template exam from her teacher, we will be focusing on specific problem areas to make sure she does well on the next exam."
"The student is going to study and come with specific questions as well as past and practice exams for our next session on Tuesday at 2 p.m."
"The student and I continued our review on topics that will be on her upcoming exam. We focused on stereochemistry and electrophilic aromatic substitution."
"We discussed carbonyl addition reactions and how to synthesize the precursors. This knowledge was then applied toward synthetic practice problems."
"We worked out old test problems that covered nomenclature and different reactions that used different reagents/catalysts."
"We covered basic carbohydrate chemistry, nomenclature, hemiacetal formation, and acetal formation. We worked on and completed his carbohydrate chemistry worksheet."
