Chemistry tutor in Chicago, IL

Student and Tutor reviewed key concepts from the Student's recent chemistry resonance test. They worked through problems on hybridization, determining correct chemical formulas and pi bond counts, drawing structural isomers for various compounds (including alkanes, alkynes, and dienes), and constructing accurate resonance structures with proper charge conservation. The Student has an opportunity to retake the test tomorrow.

The Student and Tutor reviewed core organic chemistry concepts including hybridization, resonance, and calculating formal charges, with a particular focus on drawing resonance structures for various compounds. They worked through examples from a worksheet, including a complex problem, and verified the Student's completed assignments. The Student also shared details about their organic chemistry textbook and upcoming topics, as well as an upcoming retake test that will cover these concepts.

The Student and Tutor reviewed several organic chemistry concepts through problem-solving. Topics included molecular hybridization, Newman projections, relative acidity of compounds, identifying valid resonance structures, and interpreting IR and Mass Spectrometry data. They planned to resume their session after a short break to continue with cyclohexane conformers.

The Student and Tutor reviewed fundamental concepts in Chemistry, including the principal, azimuthal, magnetic, and spin quantum numbers, as well as Hund's Rule of Maximum Multiplicity, the Aufbau principle, and Pauli's Exclusion Principle. The student practiced drawing orbital diagrams and writing electron configurations for elements like oxygen and sodium. Homework involving a practice sheet on these topics was assigned, with a follow-up class scheduled for Monday and a discussion about potential weekend morning classes.

The tutor introduced Avogadro's number and the mole concept, explaining their significance in relating macroscopic mass to the number of particles. The student practiced calculations involving mole conversions, including determining the number of atoms from moles and converting between mass and moles using molar mass. The next session will continue with practice problems, and the student will complete specific problems from a worksheet focusing on these concepts.

The Student and Tutor reviewed homework on ionic compound nomenclature, identifying and correcting minor errors. The session then introduced multivalent metals, explaining how to write chemical formulas from names using Roman numerals, and subsequently how to deduce the Roman numeral from the formula. The class concluded with an introduction to polyatomic ions and a homework assignment on multivalent ions, with plans for a review game and further polyatomic ion study in the next session.
