Recent Tutoring Session Reviews
"Today we reviewed stereochemistry of organic compounds, radical reactions involving alkanes, and stability of carbocations. The student was able to understand the topics presented and relate our discussion to class materials. We discussed future meetings in the next coming week."
"Today we started the lesson with naming chiral compounds, followed by some cis/ trans isomer problems, amine inversions, and recognizing meso compounds. We ended the lesson with an introduction to substitution reactions, including the SN2 mechanism."
"Today we went through roughly half of the student's practice set, which included lots of addition with Grignard reagents and the reduction and oxidation of carbonyl compounds. I advised her to create a master key of all reactions which can be easily referenced for future problems/studying."
"Today, the student and I worked on protective groups, Grignard exceptions (acyl substitutions and carboxylic acid derivatives), EAS overview, activating vs directing and the odd halogens, esters and ester synthesis, reduction reactions with mechanisms, synthesis problems, and reactions with labeled atoms overview."
"Today, we covered acid-base equilibria and its direction based on the pKa of the acid and conjugate acid at hand. We also reviewed acid strength for molecules containing different electronegative atoms and the trends for these acids based on the periodic table. In addition, we reviewed how to draw Lewis structures of cations and anions. I hope that the student understands the material better than she did before. We practiced some homework problems related to the material we discussed. Even though she is worried about her knowledge of the previous general chemistry, I think she performs very well in this subject matter as it relates to Organic Chemistry. I look forward to meeting with her next week!"
"Today, we covered more reactions pertaining to synthesis of alcohols, knowing when an E2 or an Sn2 reaction happens, and the stereochemical/ regiochemical consequences of these reactions. We also went over more practice problems that could show up on the midterm in terms of difficulty. The student understands stereochemistry and the visual aspect of determining R and S designation very well. He needs to spend time before the midterm on Tuesday memorizing what reagents do to certain reactants, because most of the midterm will probably contain problems that involve predicting products and multi-step syntheses."
