Recent Tutoring Session Reviews
"The student and I looked through specific problems from a sample final exam: aldol addition problems, aromaticity, additions to benzene rings, reaction mechanisms, donating/ withdrawing groups, and the difference between pi and sigma donating/ withdrawing, cyclization of di-ones."
"We started off matching compounds with their proton NMRs (number of distinct signals, position and splitting patterns), then predicting the number of distinct hydrogens and their splitting patterns for several organic compounds. She will be checking with her professor tomorrow on how deeply he wants to go into enantiotopic and diastereotopic hydrogens, because the last compounds had some of these. We finished off with working on a review of online homework, which was an introduction to Grignard and lithium reagents reacting with carbonyl compounds (ketones, aldehydes, and esters) as well as a coupling reaction between lithium dialkyl cuprates and alkyl halides."
"Today the student and I worked through problems from the book, focusing on conjugated systems. Topics we covered included: allylic vs. tertiary vs. secondary vs. primary radical and carbocation stability, how to determine if a compound is aromatic or antiaromatic, and a bunch of reaction problems with anti-Markovnikov and Sn2 mechanisms."
"We covered material to prepare her for her final. Mainly over SN2, Sn1, E2, and E1 reactions. Her exam is tomorrow so I also gave her advice on how to prepare for the final in addition to her study guide that she has."
"We covered 2 major synthesis concepts and we did 20-30 questions. The student showed a great deal of improvement by the end of the session."
"We covered questions from textbook and problem set. Variety of concepts were discussed, Newman projection, elimination, synthesis starting from alkynes, radical halogenation and mechanism of ring expansion and contraction. The students practiced questions regarding ring contraction and expansion."
