AS Modules

AS 1: Basic Concepts in Physical and Inorganic Chemistry

This module contains units on atomic structure and bonding as well as the shapes adopted by molecules and ions and the intermolecular forces existing between them. There is a general introduction to the Periodic Table with an in-depth study of Group VII. Redox reactions are introduced while analytical chemistry consists of acid-base titrations. Basic calculations and equations are an integral unit of this module.

AS 2: Further Physical and Inorganic Chemistry and Introduction to Organic Chemistry

Organic chemistry forms a major part of this unit with work on the chemistry of alkanes, alkenes, haloalkanes and alcohols. There is a qualitative introduction to equilibrium and kinetics while thermochemistry is covered in some depth. The analytical chemistry aspects are covered by ir spectroscopy and qualitative analysis. There is also further work on basic calculations.

AS 3: Internal Assessment

Section A consists of two practical tasks each worth 25 and 29 marks respectively. Section B has a planning exercise worth 20 marks and a number of other questions testing knowledge of practical techniques, observations and calculations worth 16 marks.

A2 Modules

A2 1: Periodic Trends and Further Organic, Physical and Inorganic Chemistry.

Further development of equilibrium and kinetics is included in this module and there are also units on Lattice Enthalpy and Entropy. The study of organic chemistry is continued with units on isomerism, aldehydes and ketones, carboxylic acids and esters, fats and oils. Periodic Trends and environmental chemistry complete this module.

A2 2: Analytical, Transition Metals, Electrochemistryand Further Organic Chemistry

Analytical chemistry is developed through units on mass spectrometry, nmr spectroscopy, volumetric analysis, colormetry and chromatography. The inorganic chemistry studied is based mainly on Transition metals with specific reference to Cr and V. Organic nitrogen compounds form the backbone of the work on organic chemistry with a final unit on polymer chemistry.

A2 3: Internal Assessment

This is a practical examination consisting of a planning exercise (20 marks) and practical exercises (50 marks).
