innovative Chemistry Tutor Enhancing Learning Through Interactive and Creative Teaching Approaches

Student and Tutor reviewed IUPAC naming rules for cyclic compounds, focusing on priority sequences and alphabetical ordering of substituents. They also discussed cis/trans isomerism and the relative stability of cycloalkanes, highlighting cyclohexane's chair conformation. The session concluded with an introduction to drawing and understanding the stability of substituents in chair conformations, with plans to continue this topic in the next session.

The Student and Tutor worked through a general chemistry assignment, practicing how to calculate the concentration of a weak acid and its acid dissociation constant (Ka) from titration data. They also reviewed the conceptual basis for each step, including identifying the equivalence and half-equivalence points. The Student will send a PDF on acids and bases from their lecture for discussion in the next session.

The Student and Tutor reviewed key concepts in Chemistry, focusing on Thermodynamics, specifically entropy and its factors, the Third Law of Thermodynamics, and calculations for entropy changes. They practiced numerous problems involving predicting entropy signs, calculating entropy of the system, surroundings, and universe, and determining reaction spontaneity. The session served as preparation for an upcoming test.

Student and Tutor thoroughly reviewed and practiced Le Chatelier's Principle and equilibrium calculations using ICE tables in Chemistry. They applied formulas for KP and KC, and then transitioned to thermodynamics, discussing spontaneity, enthalpy, entropy, and Gibbs Free Energy, along with the second law of thermodynamics. The session concluded with practice problems on calculating Gibbs Free Energy and plans to continue thermodynamics revision and problem-solving in the next class.

Student and Tutor worked on chemical equilibrium problems, including calculating the overall equilibrium constant (KC) for a target reaction from component reactions. They also predicted reaction direction by comparing the reaction quotient (QC) to KC and determined the extent of reactions based on KC values. The session concluded with an introduction to ICE tables for calculating equilibrium partial pressures (KP), with plans to cover Le Chatelier's principle in the next class.

Student and Tutor reviewed a chemistry exam, focusing on specific organic chemistry concepts where the Student lost points. Topics covered included conjugated pi systems, electrophilic aromatic substitution, Diels-Alder reactions (stereochemistry, s-cis/s-trans conformations, intramolecular reactions), and detailed reaction mechanism drawing with transition states. They plan to continue reviewing the remaining exam questions and practice more intramolecular Diels-Alder problems in their next session.
