Sunitha and Ifadha reviewed acid-base chemistry, covering Bronsted-Lowry definitions, strong and weak acids/bases, pH calculations, and the use of indicators. Ifadha practiced identifying acids and bases in reactions and calculating pH values. They scheduled the next class for Wednesday and discussed Ifadha's potential absence on Saturday.

Simran is teaching Raza organic chemistry concepts, including click reactions, ozonolysis, sigmatropic rearrangements (specifically Claisen and Cope rearrangements), and nucleophilic aromatic substitution (SNAr). SNAr requires electron-withdrawing groups (EWGs) in the ortho/para positions to the leaving group to stabilize the intermediate formed during the addition-elimination mechanism. Fluorine is a good leaving group in SNAr. The discussion emphasizes identifying nucleophiles, leaving groups, and EWGs, and drawing resonance structures to understand reaction mechanisms.

Simran tutored Raza on cycloaddition reactions, including Diels-Alder, ozonolysis, and click chemistry, with a focus on mechanisms, stereochemistry, and product prediction. Raza practiced identifying dipoles/dipolarophiles and determining the number of products based on symmetry. Next session will cover sigmatropic rearrangements and SN reactions.

Simran and Raza discussed electrocyclic and cycloaddition reactions, with a strong emphasis on the Diels-Alder reaction, covering diene/dienophile requirements, stereochemistry, and the endo rule. They worked through examples of identifying s-cis conformations and predicting products with correct stereochemistry. Raza was assigned practice questions on Diels-Alder reactions for the next session.

Iliana is tutored by Aashima on electrolysis, redox reactions, and corrosion in preparation for an exam. They cover factors influencing electrolysis (electrochemical potential, concentration, electrode type), competition between species at electrodes (water vs. ions), and corrosion, particularly rusting of iron. They also discuss corrosion prevention methods, oxidation numbers, oxidizing/reducing agents, and balancing redox reactions. Iliana clarifies her understanding of key concepts like inert vs. active electrodes.

Anjali tutored Ashley on the preparation of alcohols from alkenes, covering hydration, hydroboration-oxidation, and mercuration-demercuration. They reviewed Markovnikov's rule, anti-Markovnikov's rule, carbocation stability, and stereochemistry, including syn and anti addition. They worked through examples, and plan to continue with the remaining alcohol preparation methods next session.
