You will complete a written exam that lasts for 100 minutes for each of units 4 and 5. For unit 6 you will be internally assessed on four aspects of your practical work, as in unit 3, with activities a, b, c and d.

In this unit students make a quantitative study of chemical kinetics and take further their study of organic reaction mechanisms. The topics of entrophy and equilibria show how chemists are able to predict quantitatively the direction and extent of chemical change. The organic chemistry in this unit covers carbonyl compounds, plus carboxylic acids and their derivatives. Students are required to apply their knowledge gained in units 1 and 2 to all aspects of this unit. This includes nomenclature, ideas of isomerism, bond polarity and bond enthalpy, reagents and reaction conditions, reaction types and mechanisms. Students are also expected to use formulae and balance equations and balance equations and calculate chemical quantities.
Assessment: Examination of 1 hour 40 minutes in three sections
Section A: objective test questions
Section B: mixture of short answer and extended answer questions
Section C: data questions, with use of a data booklet

In this unit the study of electrode potentials builds on the study of redox in unit 2, including the concept of oxidation number and the use of redox half equations. Students will study further chemistry related to redox and transition metals. The further organic chemistry section of this unit focuses on arenes and organic nitrogen compounds such as amines, amides, amino acids and proteins. Students are expected to use the knowledge and understanding of organic chemistry that they have gained over the whole GCE in Chemistry when covering the organic synthesis section. This unit draws on all other units within the GCE in Chemistry and students are expected to use their prior knowledge when learning about these areas. Students will again encounter ideas of isomerism, bond polarity and bond enthalpy, reagents and reaction conditions, reaction types and mechanisms. Students are also expected to use formulae and balance equations and calculate chemical quantities.

Section B: mixture of short answer and extended answer questions
Section C: contemporary context questions

This unit contains practical assessments that cover the content of units 4 and 5. There is no specific content for this unit. The practical assessments cover the areas of physical, organic and inorganic chemistry. The types of practicals that students must complete are qualitative observations, quantitative measurements and preparations. There is the opportunity for students to undertake a multi-stage experiment, which includes the quantitative measurement and preparation in a longer assessment.
Students’ laboratory skills are tested in four different ways, through a choice of activities and pathways. The four activities must cover the areas of physical, organic and inorganic chemistry.
