Chemistry 7405/3 June 2018

The exam evaluates advanced chemistry topics, including reaction kinetics, rate equations, and experimental design for determining reaction orders. It covers Period 3 oxides′ properties, their reactions, and melting point trends. Organic synthesis processes such as the preparation of cyclohexene, purification methods, and product identification through spectroscopy are explored. Analytical sections assess enthalpy changes, neutralization reactions, and error minimization in calorimetry. Practical questions address chromatography for separation, functional group analysis using IR spectroscopy, and molecular retention times. The paper emphasizes problem-solving, quantitative reasoning, and integrating theoretical principles with experimental applications in chemistry.
