The exam emphasizes organic and physical chemistry, exploring reaction mechanisms, enthalpy changes, and equilibrium. Topics include nucleophilic substitution in bromoethane, combustion calculations for cyclohexane, and catalytic effects in methanol production. Analytical tasks involve distinguishing organic compounds through chemical tests, determining atom economy, and calculating masses for reaction stoichiometry. Structural aspects are analyzed in hydrogen bonding, propene isomer formation, and skeletal formulae of dicarboxylic acids. Applications cover pollutant reduction in combustion, greenhouse gas effects, and expansion factors for refrigerants. Quantitative skills are integrated through molarity, energy calculations, and volumetric analysis in reaction setups and thermal properties.
