Experience Interactive Chemistry Tutor with Diverse Expertise and Engaging Teaching Approach

During a recent lesson, an instructor and a student delved into Lewis structures, hybridization, bond angles, formal charges, valence bond theory, dipole moments, intermolecular forces, functional groups, and resonance structures. The learner, a student at Cal Poly Pomona, actively practiced identifying functional groups and drawing resonance structures, receiving valuable corrections and guidance. For continued practice, the instructor assigned additional resonance structure problems and arranged a follow-up lesson to discuss chapter 3.

The instructor and the student, a dedicated learner at Amberton University in Garland, reviewed organic chemistry concepts, including structural isomers, sigma and pi bonds, hybridization, and acidity/basicity. The student worked through integrated problems and identified factors affecting acidity and basicity. The instructor assigned practice questions from chapters one and two for the next lesson and planned to focus on chapter three on Monday.

Tanya led a chemistry lesson for an individual, a student at Golden West College in Huntington Beach, covering constitutional isomers, pKa values, and dissociation constants. They also delved into factors affecting anion stability, with the learner actively practicing how to identify stronger acids based on pKa values and anion stability. Their next lesson will continue with chapter 3, focusing on the stability of anionic species, and practice problems were assigned as homework.

This lesson with Tanya focused on the Brønsted-Lowry acid-base concept, covering the identification of acids, bases, and their conjugate pairs in chemical reactions. The student, who attends the University of Arizona in Tucson, then practiced drawing reaction mechanisms and labeling species. Errors in previous homework on resonance structures were also identified and corrected. Tanya assigned additional practice questions and scheduled follow-up lessons to prepare for the upcoming test.

Tanya and a student from Charlotte worked on understanding resonance structures in organic chemistry, focusing on conjugation conditions, electron movement, and formal charge determination. The learner practiced drawing various resonance structures and received clarification on valency and bond-line notation. Tanya assigned practice questions to be completed before their next two-hour lesson on Wednesday.

Tanya tutored Darlene on conformational isomerism, covering sawhorse and Newman projections, eclipsed, staggered, and gauche conformations, and chair conformations in cyclohexane. Darlene practiced drawing Newman projections and determining the most stable conformations of various molecules. They also discussed ring flipping in chair conformations and how it affects stability, with plans to cover energy diagrams in the next session.
