Chemistry Tutor: Specializing in Biochemistry, Organic Chemistry, Exam Preparation

Student and Tutor continued their discussion on organic chemistry, delving into the principles of Infrared (IR) spectroscopy. They reviewed the electromagnetic spectrum, molecular vibrations, and the interpretation of IR spectra, focusing on identifying characteristic peaks for various functional groups like alkanes, alkenes, alkynes, aromatics, alcohols, amines, aldehydes, ketones, and esters. The session concluded with plans to practice more questions and cover the remaining functional group aspects in the next class.

The tutor and student reviewed Mass Spectrometry, covering its principles, ionization methods, mass analyzers, and how to interpret mass spectra. They practiced identifying molecular ions, base peaks, and fragment ions for various organic molecules, including alkanes, alcohols, amines, and carbonyl compounds, focusing on fragmentation patterns and characteristic isotopic peaks for halogens.

The Student and Tutor engaged in an extensive Organic Chemistry session, focusing on multi-step synthesis problems involving aromatic compounds and complex reaction mechanisms, including the use of Grignard reagents. They also practiced drawing structures with specific R/S stereochemistry and applying IUPAC nomenclature rules for various organic compounds. The session concluded with a plan to continue the stereochemistry assignment in the next class.

The Student and Tutor reviewed the concept of strain in cycloalkanes, discussing angle strain, torsional strain, and steric strain across various ring sizes from cyclopropane to cyclohexane. They focused extensively on the chair conformation of cyclohexane, practicing drawing structures, identifying axial and equatorial positions, and understanding ring flips. The session concluded with an introduction to 1,3-diaxial and gauche interactions, and the Student was advised to revise the concepts before the next class, where they plan to complete related assignments.

The Student and Tutor worked through an organic chemistry assignment, completing multiple reaction questions and detailing the mechanisms. They focused on electrophilic aromatic substitution, reduction, oxidation, ether cleavage, and radical addition reactions, along with analyzing the feasibility of multi-step syntheses. They plan to continue with the remaining questions and a new assignment in the next session.

Student and Tutor reviewed the nomenclature of cycloalkanes, including how to name rings with various alkyl and halogen substituents, and the rules for numbering and alphabetical prioritization. They also covered cis-trans isomerism, understanding how restricted bond rotation impacts stereochemistry in cyclic structures. The next session is planned to cover angle strain and torsional strain.
