Recent Tutoring Session Reviews
"We reviewed carbonyl reactions. We also went over grignard reactions, diels alders reactions, the wittig reaction, acidity and basicity, and briefly covered spectroscopy."
"Today, the student and I reviewed free radical halogenation chain reactions, bond dissociation enthalpies, reaction kinetics and rate equation We also discussed activation energy and transition states."
"Today we worked on nomenclature. We went over practice problems that involved naming given structures and drawing structures from given names. The student was able to handle all of the problems, with only occasional difficulties with uncommon or ambiguous naming conventions. Next week we will focus on isomers and stereochemistry."
"Today we covered stereoisomers, enantiomers, diastereomers, meso compounds, and E/Z configuration. The student understood the material better after we went over it."
"For today's session we went over a homework assignment that covered various topics. For example, we touched on electronegativity, polarity, molecular/ electron configuration, and solubility. Seeing as the student's professor has not gone over this material in detail (this was upcoming material), she initially struggled with all of the concepts, but after a few examples and some explanation she felt considerably more confident about the material. It is evident that she is a very capable student, but her intimidation by chemistry somewhat impedes her ability to see that. Like many of my other students, I work to positively reinforce students work processes rather than punish them, which I strongly believe will help her comfort with the material. I can see her improving as the sessions progresses, and I am very excited to keep working with her in future lessons."
"For the final review, we went over some of the practice exam problems, talked about electrophilic addition to benzene rings, and the effects different constituents have, some reactions with amines."
"Today we discussed protein metabolism, mechanism for DNA methylation and DNA acylation, acetoacetic-ester synthesis (and how to make different ketones), strecker synthesis for making amino acids, Gabriel synthesis, Hoffman degradation, saponification of triacylglycerols and esters, fatty acid synthesis, and beta oxidation. We also went over key concepts within those topics that were relevant to the MCAT (for instance where certain functions occur in the cell). The student's attitude was very positive (as usual). She asked great questions and was able to explain clearly her reasoning to the questions that I asked her. I gave her numerous study strategies and tips for the MCAT which she will be taking this Saturday."
"The student and I went over molecular orbital theory, nomenclature, and drawing structures today. She seems extremely prepared for her exam tomorrow, and today focused mostly on review and clarifying a few points she may have forgotten from general chemistry (such as the sum of the vectors). I'm excited to meet with her on Friday to discuss new class material."
"I helped the student do the homework the problems recommended by his professor in preparation for his first test in organic chemistry. We went over Newman projections, distinguishing different types of isomers, and an introduction to reaction mechanisms. He was enthusiastic and receptive and appeared to make gains in mastering the material. I presented him with a few strategies for remembering relative reaction rates based on the relative stability of intermediates."
"During this session, we focused most heavily on the concept of molecular dipoles. We applied the concept of electronegativity differences in covalent bonds to map the dipole for each bond within a molecule, and used these in order to determine the approximate directionality of the net molecular dipole. Towards the end of the session we were also able to discuss intermolecular forces and then resonance briefly. Our main tool was a mock problem set, which I created to reflect the structure and types of problems that the professor provides the students. The student seemed encouraged and ready to understand the material we covered in regards to dipoles, and seemed to have an understanding of them by the end of the session. She seemed more confident with intermolecular forces, and understood that problem fairly readily."
"We covered naming of molecules with different types of functional groups and reactions pertaining to these FGs. The student needed help most with naming since each functional group has different rules and nomenclature. The student did really well catching on to the difficult material and scored well on her homework."
"The student and I discussed acid/base chemistry as it relates to organic compounds and or ions. I mentioned to her about how the same principles apply as far as the overall acid/ base strength (weaker acid - stronger conjugate base, etc.), stability of ions in relation to acid/ base strength. I think she understood acid base theory from a general chemistry standpoint, but needed a little help relating this to organic chemistry. We then delved into nomenclature and I explained how to name alkanes based on IUPAC rules."
