CHEMISTRY (EDEXCEL)
A2 COURSE OUTLINE
What is A2 Chemistry?
The chemistry studied here goes beyond that of the AS course, expanding on many of the AS topics and introducing others which are entirely new.
New topics include aromatic compounds, carbonyls, condensation polymers and transition elements. Amongst the new concepts introduced are chirality, entropy and electrode potentials.
Candidates learn more about physical analytical techniques, and how the information they provide can be combined to enhance the breadth and depth of a chemist's problem-solving skills.
Applications to everyday contexts are always emphasised and students will learn about the invaluable contribution chemistry makes to modern life, not only in terms of the analytical processes it provides, but the ever-improving materials it develops, including pharmaceuticals. Ongoing research in chemistry is currently, amongst many diverse areas of study, contributing to the understanding of climate change, developing green chemistry, attempting to produce medicines with improved pharmacological activity and fewer side-effects, and investigating the use of fuel cells as energy sources for electric cars and space vehicles. All of these, and more, feature in the recently-revised A-level specification.
Candidates will need to develop the skill of bringing together concepts and knowledge from different areas of chemistry and applying them in particular contexts, some of which may be unfamiliar.
What do I need to get before I start the course?
You will be advised about this when you have your interview; your personal goals will determine when you start the A2 and whether or not any AS units should be repeated.
Candidates will require slightly more advanced mathematical skills than are strictly essential for AS Chemistry.
| A2 Specification and Scheme of Assessment | |
|
Unit 4 |
Kinetics, Entropy, Equilibrium Constants, Acid-Base Equilibria, pH and Buffers. Chirality, Carbonyls, Carboxylic Acids and Derivatives. Analytical Techniques - Chromatography and Spectroscopy. |
|
Unit 5 |
Redox Reactions, Electrode Potentials, Chemistry of Transition Elements. Arenes, Amines, Amides, Amino Acids, Proteins, Polyesters, Polyamides and Organic Synthesis. |
|
Unit 6 |
Candidates carry out at least three assessed practical tasks, one qualitative (observation), one quantitative (measurement) and one preparation in addition to being assessed in General Practical Competence. |
Structure of the Course
This course will be taught for 6 lessons per week. 1.5 hours every fortnight will be set aside for practical work, and practical skills will be developed and assessed in these lessons. Homework is set after each class and is an essential part of the course. Mock exams take place each month.
