Experience Interactive Chemistry Tutor with Diverse Expertise and Engaging Teaching Approach

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.

Tanya tutored Darlene on advanced IUPAC nomenclature, focusing on identifying and naming complex substituents and applying these rules to complicated organic molecules. Darlene practiced naming compounds and drawing structures from IUPAC names. They discussed potentially continuing sessions to cover spectroscopy and Newman/Sawhorse projections, with Darlene considering resuming lessons after starting college.

Tanya and Darlene discussed acid-base chemistry, focusing on quantifying acid strength using Ka and pKa values, and factors affecting acidity like atomic size, electronegativity, and hybridization. Darlene practiced ordering compounds by acidity. They agreed to continue the discussion on conjugate bases, resonance, and inductive effects in the next session on Sunday at 4:30.

Tanya is tutoring Darlene in Bronsted-Lowry acid-base chemistry. She covers proton donors/acceptors, conjugate acid-base pairs, reaction mechanisms (electron movement), relative acid/base strengths, and how these factors influence equilibrium in reactions. They work through examples and practice problems, focusing on identifying acids, bases, and predicting reaction direction.

Tanya Gupta tutored Darlene Thieu on resonance structures, formal charges, and chemical bonding, including identifying ionic, polar covalent, and non-polar covalent bonds. Darlene practiced applying stability rules to resonance structures and determining bond types in various molecules. Tanya assigned practice problems for determining molecular formulas and scheduled the next session for Wednesday at 6 p.m.

Tanya is tutoring Zoila in chemistry, covering heat calculations (including phase changes, unit conversions, and cooling curves), acid/base chemistry (KW, concentration, strength), and intermolecular forces (dispersion, dipole-dipole, and hydrogen bonding). Tanya emphasizes using correct formulas, paying attention to units, and understanding the underlying concepts. The tutoring session concludes with Tanya explaining hydrogen bonding using hydrazine as an example and asking Zoila for a recommendation.
