Chemistry tutor near me in Stockton, CA

The tutor and student reviewed the relationship between reaction rates and stoichiometry, then delved into integrated rate laws and their graphical representations for zero, first, and second-order reactions. They practiced calculating rate constants from half-life data, and planned to work on more kinetics problems in the next session.

The Tutor and Student reviewed Valence Bond Theory, focusing on orbital overlap, hybridization (sp3, sp2, sp), and the distinction between sigma and pi bonds. They practiced identifying hybridization, counting sigma/pi bonds in molecules like CO2 and C2H4, and discussing rotation and isomerism in single versus double bonds. Future practice on complex molecular structures was planned.

The student and tutor reviewed the mechanisms of electrophilic addition and free radical addition reactions of alkenes. They specifically delved into Markovnikov's rule and its anti-Markovnikov counterpart, the Kharasch effect, and discussed the conditions under which each occurs. The next session will cover aromatic compounds and their reactivity.

The Tutor and Student reviewed chromatography techniques, specifically column chromatography, its principles, and steps. They also covered osmosis, its definition, and types of solutions, followed by a practical application of dialysis and the use of Beer-Lambert Law related to amino acid absorbance.

The session covered the effects of substituents on electrophilic aromatic substitution reactions, including activating and deactivating groups, resonance effects, and inductive effects. The Student learned to classify substituents, predict their influence on reaction rates and regiochemistry, and name substituted benzene compounds. Friedel-Crafts alkylation and acylation were also introduced.

The Tutor and Student worked through several chemistry problems related to thermochemistry and stoichiometry. They practiced calculating heat released in combustion reactions, determining limiting reagents, and finding energy produced per gram of substance. The Tutor also provided guidance on calculating moles from mass and understanding molarity.
