  This is a structured theory paper containing seven compulsory questions, with all answers to be written in the spaces provided. The total marks for the paper is 80, and the examination has a duration of 2 hours. Candidates are instructed to show all their working where necessary and are permitted to use mathematical tables and electronic calculators.

  The paper assesses a variety of major chemistry topics through detailed, multi-part questions:

  • Organic Chemistry: A comprehensive question featuring a flowchart that tests knowledge of reactions of alkanes and alkenes, including cracking, hydrogenation, polymerization, and combustion.
  • The Mole and Stoichiometry: This includes quantitative problems on determining empirical formulae from experimental data and titration calculations to find the percentage composition of a mixture.
  • Chemical Energetics: Questions require the calculation of enthalpy changes using bond energies, application of Hess's Law with energy cycle diagrams, and calculation of enthalpy of solution.
  • The Periodic Table: A question based on a section of the periodic table tests understanding of periodic trends, electronic configuration, bonding, and physical properties of elements.
  • Industrial Processes: A detailed flowchart on the Solvay process for the manufacture of sodium carbonate is presented for analysis.
  • Carbon and its Compounds: This section covers the laboratory preparation of carbon oxides and the distinct properties of the allotropes of carbon (graphite and diamond).
  • General Chemistry: Questions on laboratory apparatus, properties of Bunsen burner flames, and the composition of air are also included.
