Engage with a Chemistry Expert from West Chester University for Interactive Learning Journeys.

The Tutor and Student explored the gas laws (Boyle's, Charles's, and Gay-Lussac's) focusing on their theoretical understanding and relationships between variables. They then extensively covered the five postulates of the Kinetic Molecular Theory and how it explains the macroscopic behavior of gases described by the gas laws. The next session is planned for the following week.

The Student and Tutor reviewed electrophilic addition reactions of alkenes, focusing on predicting major products, stereochemistry (sin/anti addition), and regiochemistry (Markovnikov/anti-Markovnikov). They practiced identifying reaction types from reagents, understanding carbocation rearrangements, and determining the stereochemical outcome based on the presence of chiral centers, with plans for further practice on subsequent Sundays.

The student and tutor worked through several quantitative chemistry problems, including calculating concentration in various units (percent mass/volume, molarity, ppm, ppb) and applying these concepts to real-world scenarios. They also discussed theoretical concepts like the solubility of ionic compounds, Coulomb's Law, and the factors affecting London dispersion forces, with plans to continue sessions to prepare for upcoming exams.

The Student and Tutor reviewed concepts related to solubility, intermolecular forces, and molecular polarity. They explored the "like dissolves like" principle, discussed various intermolecular forces, and their impact on dissolving behavior. The session also covered definitions of acids and bases, including Arrhenius and Brønsted-Lowry theories, and touched upon the influence of size and temperature on solubility.

The student and tutor worked through challenging organic synthesis problems, focusing on reaction mechanisms for amide formation and nucleophilic aromatic substitution. They analyzed potential synthesis routes, identified key intermediates and reagents, and planned the steps needed to achieve the target molecule.

The student and tutor reviewed advanced organic chemistry mechanisms including aldol condensations, nucleophilic additions, and Robinson annulations. They practiced drawing reaction mechanisms, identifying intermediates, and understanding ring formation. The tutor provided guidance on these complex reactions, and they planned to revisit retrosynthesis for a future project.
