Recent Tutoring Session Reviews
"Yesterday the student and I spent the entire session going through her Chapter 7 Review worksheet, and then we went through the Chapter 7 key concept questions at the end of the chapter. I was incredibly impressed with her throughout the session, as she really seems to get the concepts so far. She had a positive attitude and was determined to fully understand the concepts. We worked on a T chart again dealing with Active vs. Passive transport, and I had her explain concepts back to me out loud. I saw her quiz score which was an 84% (way to go!) and her notes looked very good."
"We continued our work on the problem sets. Problem 2.2F was on a chiral allylation of propanoic acid. We talked about three different methods to introduce a stereospecific allyl group at the alpha position. One was a chiral amide alcohol that gives a place enolate with a stereospecific face the allyl bromide can add to. Then we used the chiral oxazolidinone using the same facial selectivity. Then we focused on using a chiral pie Allyl complex and attack of the dianion of the acid. Problem G. Was an advanced problem that we needed to a single carbon homologation on either a ketone using diazomethane or 1 carbon homologation of an alkyl bromide using gurnard and formaldehyde and PBr3 on the resulting alcohol. Then the two substates were enolized using either thermo or kinetic as needed to give the product Problem 3. We worked on a TiCl4 rearrangement of the cyclobutane to give a carbocation that picks up chlorine and generates an enolate that was reacted with benzaldehyde. The stereochemistry of the product was rationalized using Zimmerman Traxler Transitions, and states to show the more stable TS and the predominate product."
"We went over behaviors of gases, ideal gas law, combined gas law, Dalton's law of partial pressure, Graham's law of effusion, ideal versus real gases, solutions, molarity, molality, mole fraction, like dissolves like, colligative properties, Raoult's law, osmotic pressure, equilibrium, K, Q, Le Chatelier's principle, acid base chemistry, Arrhenius, Lewis, Bronsted Lowry, ph, poh, log formulas, conjugate base pairs, titration, and equivalence point. The student seemed happy in this "crash course" before going back to college and beginning his course."
