Recent Tutoring Session Reviews
"Today we did an overview of study strategies. We also did a review of resonances and Lewis-dot structures, how to do formal charges, ions and radicals, drawing structures, and determining the formal charges. We then went over how to calculate unsaturations in CH, CHX, and CHO containing compounds. Drawing all possible isomers. "
"We covered mechanism questions based on the student's request. The mechanism questions were based on Grignard reactions. Other retrosynthetic questions were clarified to the student. The reduction and oxidation reactions were interpreted to student with the proper mechanism. The student wanted more clarifications about nucleophilic addition to an ester, aldehyde and ketone. All the questions were clarified and interpreted to the student."
"We covered some problems from chapter 6 on reactions involving alkene bonds. I gave the student some tips on determining ways to decided which reagents to use and also I explained why some specific reagents needed to be used in the reaction they're involved in. He said that he is starting to feel more confident with his quizzes and tests and feels he has done well on the recent ones."
"We covered the naming of alkanes, alkenes, and alkynes, with special attention to cyclo groups and cis and trans isomers. We also worked on addition of strong acids to alkenes, including the products and the mechanism. We spent a little time going over good resonance structures and how to draw the arrows."
"We did a quick overview on several topics to get the student more up to speed on OChem since she took the first semester of it. We talked about electron configuration, orbitals, hybridization, acids and bases, and isomers such as constitutional isomers, cis/trans, identifying chirality and labeling enantiomers, diastereomers, naming chiral centers via R/S, and when a mirror plane results in a classifying a molecule is achiral. At the end, we also briefly reviewed chair conformations and radical reactions. The most difficult part for her was probably stereochemistry, but she seemed to understand it better by the end and I gave her a few tips on things like how to identify chiral centers, steps on how to label R/S configurations, and other useful strategies in solving problems."
"We discussed about stereochemistry, chiral and achiral compounds, optical activity, mirror plane, R and s configuration, enantiomers, diastereomers, meso compounds, enantiomeric excess, racemic mixture, SN1 and SN2 nucleophilic substitutions reactions, nucleophile, and electrophile. We solved a number questions from textbook and a quiz. I made her solve the problem first, and we solved it together if she could not. She will practice solving more problems before next session."
