Tonga Form 6 Chemistry

This course covers a range of fundamental chemistry concepts, including atomic structure, bonding, shapes of molecules, quantitative chemistry, organic and inorganic chemistry, principles of physical chemistry, and oxidation and reduction. The 2017 Tonga Form Six Certificate Chemistry exam provides insights into the specific topics covered.

Topics Covered:

• Atomic Structure, Bonding, and Shapes of Molecules: This section explores the electronic configuration of atoms and ions, valence electrons, electronegativity, atomic radii trends, intermolecular forces, and molecular shapes using the electron pair repulsion theory.
• Quantitative Chemistry: This section focuses on empirical and molecular formulas, stoichiometry, and titration calculations, including the concept of standard solutions.
• Organic and Inorganic Chemistry: This section covers the nomenclature and reactions of organic compounds, including alkanes, alkenes, alcohols, aldehydes, ketones, carboxylic acids, and esters. It also touches upon the properties of inorganic oxides and their relationship to the periodic table. The exam included questions on isomerism (cis-trans isomers), substitution reactions, addition reactions, and oxidation reactions of organic compounds.
• Principles of Physical Chemistry: This section delves into enthalpy changes, energy profile diagrams, the role of catalysts, and dynamic equilibrium, including Le Chatelier's principle and the effect of changing conditions on equilibrium.
• Oxidation and Reduction: This section covers the definitions of oxidation and reduction in terms of electron transfer and changes in oxidation states. It also includes balancing redox reactions and identifying oxidizing and reducing agents.

It is important to note that this information is based on the 2017 exam and may not represent the complete current curriculum. Additional resources, such as official syllabi or more recent exam papers, would be needed for a more comprehensive overview.
