The exam assesses organic and physical chemistry, including reaction mechanisms, spectroscopy, and equilibrium. Topics include triester hydrolysis, coconut oil analysis, and the environmental impact of bioethanol as a fuel. It covers enthalpy of combustion, benzene stability, and nitration mechanisms. Equilibrium concepts address Kc calculations and diester reactions. Spectroscopy focuses on NMR, IR, and structural elucidation of isomers. Reaction mechanisms such as esterification, cracking, and free-radical substitution are explored, along with kinetic studies of iodine and propanone reactions. The paper emphasizes practical applications, theoretical understanding, and data analysis in chemical contexts.
