Chemistry 9701/06 Oct Nov 2002 | Cambridge AS Level Past Papers With Mark Scheme

1. Organic Chemistry: Examining the formation of disaccharides from glucose, explaining intermolecular bonding for glucose solubility in water, and understanding the processes in glycolysis involving glucose-6-phosphate formation.
2. Enzyme Kinetics: Understanding enzyme-catalyzed reaction rates, the Michaelis constant (Km), and how inhibitors and cofactors alter enzyme activity in biochemical reactions.
3. Environmental Chemistry: Exploring the effects of agricultural practices on coastal ecosystems, including oxygen depletion in waters, algae growth, and the decline of fish species like cod.
4. CFCs and Ozone Depletion: Investigating the role of CFCs in ozone layer depletion, explaining their properties and environmental impact, and the replacement of CFCs with less harmful compounds like HCFC-123.
5. Physical Chemistry: Analyzing phase equilibria and the intermolecular forces in hydrides of Group VI, applying Raoult's Law, and calculating partition coefficients for solute distribution in organic and aqueous solvents.
6. Spectroscopy: Studying UV/visible absorption in organic molecules, identifying absorption transitions, and analyzing mass spectra and IR spectra to deduce molecular structures and fragmentation patterns.
7. Transition Elements: Investigating the electrochemical purification of copper, the behavior of manganese in different oxidation states, and the disproportionation of manganese oxo-anions in acidic solutions.
