Chemistry 7405/2 June 2022

The exam evaluates organic and physical chemistry, focusing on reaction mechanisms, kinetics, and spectroscopy. Topics include rate equations for butanone reactions, activation energy calculations, nucleophilic addition, and equilibrium constants for tetrafluoroethene synthesis. Analytical sections explore NMR, IR spectroscopy, and molecular structure determination. Organic chemistry covers polymerisation, ester hydrolysis mechanisms, and the Friedel–Crafts acylation of benzene. Practical applications include preparing hexan-2-ol, purifying products, and calculating yields. Environmental considerations of chlorofluorocarbons and their alternatives are examined. The paper emphasizes theoretical understanding, quantitative problem-solving, and practical skills in organic and physical contexts.
