Robert and Mary-Walter worked through organic chemistry problems, including reactions with cyclohexene, acidic cleavage, and a challenging mechanism involving dioxane. They identified and corrected an initial incorrect assumption about product ratios based on mechanistic analysis. They planned to continue problem-solving in the next session.

Robert and Mary-Walter delved into the world of ethers and epoxides during their recent organic chemistry lesson. Their discussion encompassed nomenclature, the industrial preparation of diethyl ether, Williamson ether synthesis, and aloxxymercuration-demercuration. Mary-Walter actively engaged by working through problems to identify optimal reagents for ether synthesis, with a particular focus on SN2 reactions and the impact of steric hindrance. Looking ahead, Mary-Walter intends to review reactions from Orgo 1 and compile a comprehensive reaction sheet for Orgo 2. They have arranged their next lesson for Friday to continue their exploration of ethers and epoxides.

Robert assisted a University of Toronto student in preparing for an organic chemistry final exam. The lesson covered a thorough review of reagents, spectroscopy techniques (IR, Mass Spec, CNMR, HMR), and reaction mechanisms. The learner actively practiced applying these concepts to example problems and clarified specific areas of confusion. They also discussed effective strategies for the exam, such as focusing on key concepts and avoiding getting stuck on challenging problems. As a follow-up, it was agreed that the student would review reagents and past exams.

Stressed about an upcoming organic chemistry exam, a student from Escondido sought help from Robert. They reviewed acids and bases (Lewis vs. Bronsted-Lowry), stereochemistry (R/S configurations), Lewis structures, amino acid ionization, Newman projections, and chair conformations. Robert emphasized practice questions, time management strategies for the exam, and understanding concepts for long-term improvement. They planned another review lesson.

A student from UCLA in Brentwood recently reviewed advanced organic chemistry concepts. The lesson focused on topics such as resonance, Diels-Alder reactions, and various synthesis strategies, all in preparation for an upcoming exam. They worked through specific problems, emphasizing electron movement, stereochemistry, and reaction mechanisms. The learner has an exam scheduled for next Tuesday, with a final exam following on Friday.

Robert assisted Isabella with understanding aromatic substitution reactions, including activators and deactivators, and Friedel-Crafts limitations. They worked through synthesis problems, including Grignard reactions. Isabella was assigned synthesis practice problems and they scheduled a follow-up session to discuss the Diels-Alder reaction.
