Chemistry Tutor: Specializing in Biochemistry, Organic Chemistry, Exam Preparation

The Student and Tutor reviewed alcohol protecting groups, diol cleavage, tosylation, ester reduction, and the Appel reaction. They worked through multi-step synthesis problems, focusing on reaction mechanisms and product prediction. The session concluded with a discussion of protecting ketones and using Grignard reagents.

The Student and Tutor reviewed concepts related to dienes and Diels-Alder reactions, including electron donating/withdrawing groups, S-cis/S-trans conformations, and HOMO/LUMO analysis. They also practiced identifying thermodynamic and kinetic products in reactions with symmetrical and unsymmetrical dienes. The Student was assigned a problem to practice applying these concepts.

The tutor and student worked through various chair and half-chair conformations of cyclic organic molecules, focusing on fused ring systems, cis/trans fusions, and the stability of substituents. They practiced drawing these conformations and identifying the most stable ones, with plans to continue this practice in future sessions.

The tutor and student reviewed various conformational analyses, including eclipsed and bisected forms of alkenes and chair conformations of cyclic systems like steroids. They practiced drawing these structures and discussed factors affecting their stability. The next session was scheduled to cover remaining questions.

The Student and Tutor reviewed conformational analysis of cyclic organic molecules, including cyclohexane derivatives with double bonds and heteroatoms. They practiced drawing and analyzing chair and half-chair conformations, explored the anomeric effect, and analyzed fused ring systems to determine the most stable conformers. The session concluded with plans to review bisected and eclipsed conformations.

The Student and Tutor reviewed concepts in organic chemistry, including molecular orbital diagrams, electrophilic addition reactions with kinetic and thermodynamic products, SN1 reactions and resonance, nodes in molecular orbitals, HOMO/LUMO identification, and cycloaddition reactions like the Diels-Alder. They practiced identifying these concepts through several example problems and discussed next steps for scheduling.
