The exam emphasizes organic and physical chemistry topics, including reaction kinetics, equilibrium principles, and thermochemistry. Key themes involve catalytic effects, Maxwell-Boltzmann distributions, and collision theory. Practical applications include titration for citric acid purity, enthalpy calculations for acid-base reactions, and structural isomer comparisons of hydrocarbons. Analytical skills are tested through empirical and molecular formula derivation, mass spectra analysis, and bond absorption in IR spectroscopy. Mechanistic studies explore nucleophilic substitution, elimination reactions, and polymerization. Quantitative tasks include percentage purity, yield calculations, and equilibrium constant determination, integrating theoretical knowledge with experimental problem-solving in chemical systems.
