Expert Organic Chemistry Tutor with innovative teaching techniques and engaging curriculum methods.

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 Student and Tutor reviewed electrophilic aromatic substitution reactions, focusing on the mechanism, the role of activating and deactivating groups, and the directing effects of substituents on benzene rings. They worked through examples from the Student's assignment, including chlorination, nitration, and bromination, and discussed concepts like resonance and hyperconjugation. The next session will involve new assignment questions.

The Student and Tutor reviewed the definitions and properties of even and odd functions using algebraic examples. They then explored the signs of trigonometric ratios in different quadrants and applied trigonometric identities to solve a problem involving finding a trigonometric value given its reciprocal and the quadrant.

The tutor and student reviewed fundamental trigonometric ratios, their reciprocals, and methods for calculating values for standard angles. They also covered angle measurement in degrees and radians, graphical representation of angles, and the application of complementary angle identities to solve problems.

The tutor and student focused on foundational trigonometry concepts, including the definition of trigonometric functions in right-angled triangles and the calculation of sine, cosine, and tangent ratios. They also practiced identifying triangle sides based on the angle of consideration and briefly reviewed the Pythagorean theorem.

The Student and Tutor discussed IR spectroscopy, focusing on the interpretation of IR spectra and the identification of different types of molecular vibrations. The student practiced matching IR spectra to different molecules based on functional group peaks. The plan is to review NMR and address any remaining questions in the next session; the student will send practice problems beforehand.
