Fostering scientific thinking through conceptual clarity, inquiry, and real-world application.

The student and tutor reviewed calculations related to weak acid and base dissociation, pH, and pOH. They then transitioned to understanding and calculating solubility products (Ksp) for sparingly soluble salts. The student will continue practicing these concepts, with a plan to cover the common ion effect and buffers in the next session.

The Student and Tutor worked through organic chemistry mechanisms with Grignard reagents and multi-step synthesis. The Student reviewed reactions to synthesize a five-membered ring, including protection and deprotection steps and oxidation. The Student will send another problem set for review in the next session.

The Student and Tutor reviewed organic chemistry reaction mechanisms, focusing on steric hindrance, resonance, and named rearrangements such as the Fries rearrangement. They worked through problems from a practice worksheet, identifying reaction pathways and potential pitfalls. The session concluded with a challenging synthesis question regarding the addition of a methyl group, which was left for further consideration.

The Tutor and Student reviewed the chemical properties and reactions of aldehydes and ketones, focusing on the reactivity of the carbonyl group, methods of synthesis, and nucleophilic addition reactions. They also discussed the use of protecting groups and intramolecular cyclizations, particularly in the context of carbohydrate chemistry. The next sessions are scheduled for Saturday and Sunday evenings to continue these topics.

The Tutor and Student reviewed definitions and concepts of acids and bases, including Arrhenius and Brønsted-Lowry theories, acid/base strength, and the pH scale. They practiced calculating concentrations and pH for strong and weak acids, and discussed dissociation constants (Ka). Future sessions will focus on further practice questions.

The Tutor and Student reviewed several organic chemistry concepts including nucleophilic aromatic substitution, oxidation reactions (Swern oxidation), rearrangements (Cope rearrangement), electrophilic addition to alkenes, acidity of functional groups, and multi-step synthesis strategies. They worked through several practice problems, focusing on reaction mechanisms and regioselectivity, with plans to continue practice in the next session.
