School Science concepts taught by Himani

Student learned about 4 hours ago

The Student and Tutor reviewed basic chemistry concepts including electron shell filling rules and the organization of the periodic table. They discussed key periodic trends such as atomic size variations across periods and down groups, elaborating on the shielding effect. The session also covered the characteristics of metals, nonmetals, and metalloids, along with an introduction to periodic table blocks. The Student practiced electronic configurations for various elements, and the Tutor planned to acquire the Student's Year 11 VCA Chemistry syllabus for the next session.

The Tutor and Student explored the fundamental concepts of the periodic table, including its organization by atomic number, periods, and groups. They also covered electron configuration, the octet and duplet rules for stability, valence electrons, and valency, which dictates the number of bonds an element can form. Homework was assigned to practice writing electron configurations for ions and an element from the periodic table.

Student and Tutor reviewed metal chemistry, focusing on coordination complexes. They discussed octahedral complexes, inner and outer sphere coordination, and kinetic lability versus inertness, applying concepts like Gibbs free energy and charge density to reaction rates. The session concluded with a detailed explanation of the complex reactivity series for transition metals, emphasizing the need to memorize specific patterns for di- and tri-positive metal ions for effective problem-solving, and the Tutor offered to send supplementary notes.

Student and Tutor reviewed the concepts of anti-Markovnikov hydration and the role of steric hindrance in hydroboration reactions. The session then moved into a detailed discussion of epoxidation, covering both electrophilic and nucleophilic mechanisms, reagent identification, and the resulting stereochemistry and regioselectivity. Dihydroxylation was subsequently explored, distinguishing between cis and trans additions, their respective reagents (KMnO4, OsO4, H2O2/acetic acid), and the underlying mechanisms. The Tutor concluded by explaining the concept of catalytic osmylation to address the practical challenges of using OsO4.
