Component Marks Duration Weighting insert text

Periodic table, elements and physical chemistry (01)

100 2 hour 15 mins 37% Assesses content from modules 1, 2, 3 and 5

Synthesis and analytical techniques (02)

100 2 hour 15 mins 37% Assesses content from modules 1, 2, 4 and 6

Unified chemistry (03)

70 1 hour 30 minute 26% Assesses content from all modules (1 to 6)

Practical endorsement in chemistry (04)

- - - Non-exam assessment

All components include synoptic assessment.

Students must complete all components (01, 02, 03, and 04) to be awarded the OCR A Level in Chemistry A.

Content overview

The six modules are each divided into key topics:

Module 1: Development of practical skills in chemistry

  • Practical skills assessed in a written examination
  • Practical skills assessed in the practical endorsement

Module 2: Foundations in chemistry

  • Atoms, compounds, molecules and equations
  • Amount of substance
  • Acid–base and redox reactions
  • Electrons, bonding and structure

Module 3: Periodic table and energy

  • The periodic table and periodicity
  • Group 2 and the halogens
  • Qualitative analysis
  • Enthalpy changes
  • Reaction rates and equilibrium (qualitative)

Module 4: Core organic chemistry

  • Basic concepts
  • Hydrocarbons
  • Alcohols and haloalkanes
  • Organic synthesis
  • Analytical techniques (IR and MS)

Module 5: Physical chemistry and transition elements

  • Reaction rates and equilibrium (quantitative)
  • pH and buffers
  • Enthalpy, entropy and free energy
  • Redox and electrode potentials
  • Transition elements

Module 6: Organic chemistry and analysis

  • Aromatic compounds
  • Carbonyl compounds
  • Carboxylic acids and esters
  • Nitrogen compounds
  • Polymers
  • Organic synthesis
  • Chromatography and spectroscopy (NMR)

Students gain practical skills throughout the course. These are assessed in the written examinations and in the practical endorsement (component 04). Activities that could count towards the practical endorsement are indicated in the specification.
