Recent Tutoring Session Reviews
"Today, we did a bit of review of what we covered last session, including bonding and molecular formulas. We spent the rest of the session going over molecular orbital theory and hybridization. We focused on drawing electron energy diagrams and 3-dimensional orbitals, with special attention to sp3 hybridized carbons (sigma bonds) and sp3 hybridized carbons (sigma and pi bonds)."
"Today, we went over reactions involving alcohols and their synthesis. We did a lot of examples for organometallic reagents regarding their involvement with making alcohols from ketones and aldehydes. We also went over how to make alcohols using Sn2 reactions. The student was starting to get it as the session went on because we did a lot of examples."
"We are reviewing organic chemistry prior to the student taking the class. We covered functional groups and naming (priority of alkenes, alkynes, halides, alkyls, hydroxyl, and higher carbonyl compounds), and we began the reactions of alkenes. I also showed her the basics of drawing chemical mechanisms."
"We continued aldehyde and ketone reactions. We focused on aldol and acetal reactions and arrow formalism. The student is struggling with combining all of the topics to form a logical synthesis. The student has a good attitude toward the material. I included strategies for predicting reaction products with less work to save time as well as how to use protecting groups in common situations. I left him with extra practice problems and associated webpages. The student feels he is making progress and wants to have more sessions in the next week before the final."
"We continued going over aromatic compounds and their reactions. We went over nitration, Friedel-Crafts alkylation and acylation, ortho/para and meta directors, etc. We spent time going over the reagents and mechanisms and limitations of these reactions. I gave a number of problems to do for practice."
"We continued going through the student's textbooks as well as going over problems she had worked on at home. I think she is grasping the material well and am excited to continue working with her."
