The exam assesses organic and physical chemistry principles, emphasizing reaction mechanisms, equilibrium, and spectroscopy. Topics include combustion and catalytic cracking of alkanes, free-radical substitution, and environmental impact of CFCs. It explores nucleophilic substitution, infrared spectroscopy, oxidation of alcohols, enthalpy calculations, and alkene dehydration. Analytical techniques cover Kc calculations, Arrhenius equation analysis, and activation energy determination. Advanced sections address benzene stability, electrophilic substitution, amino acid structures, protein bonding, DNA nucleotide assembly, and amine synthesis. The paper integrates practical applications, theoretical analysis, and structural elucidation to evaluate comprehension and problem-solving skills in organic and physical chemistry.
