Overview of the course

OCR Chemistry – The course looks at three main areas; Physical, Organic and Inorganic Chemistry. Physical Chemistry looks at the structure of atoms, bonding and factors effecting reaction rates including mathematical calculations. Inorganic chemistry focuses on specific groups of the periodic table and their properties. Organic chemistry looks at the different groups of chemicals including, alkanes, alcohols, alkenes, carboxylic acids and ketones. Amino acids and DNA is also studied in year 2 of the course allowing links with A-level Biology.

What Will You Study:

Year 12

Module 1 – Development of practical skills in chemistry

Practical skills will be assessed in written examinations. During all aspects of the course practical work will be completed and a portfolio of work collated. These experiments will be examined in the terminal exams.

Module 2 – Foundations in chemistry

Atoms, compounds, molecules and equations.

Amount of substance and acid-base and redox reactions.

Electrons, bonding and structure.

Module 3 – Periodic table and energy 

The periodic table and periodicity

Group 2 and halogens

Qualitative analysis and enthalpy changes

Reaction rates and equilibrium (quantitative)

Module 4 – Core organic chemistry

Basic concepts

Hydrocarbons, alcohols and haloalkanes

Organic synthesis and analytical techniques (IR and MS)


Year 13

Module 5 – Physical chemistry and transition elements:

Rates equilibrium and pH


Transition elements

Module 6 – Organic chemistry and analysis:

Aromatic compounds, carbonyls and acids

Nitrogen compounds, polymers and synthesis




AS Assessment: Two written papers

Paper 1 – Breadth in Chemistry (70 marks)
