What should I revise for OCR A Level chemistry Paper 2 (2024)?

How did Paper 1 go? It seems to have been not to bad a paper this year, and if you bought the predicted papers you will have found quite a few similarities (pH curve anyone?).

Topics included in A Level chemistry OCR A Paper 2

Paper 2 (synthesis and analytical techniques) focuses pretty much entirely on organic chemistry from modules 4 and 6, but it can also draw in elements from modules 1 and 2. You can get a comprehensive list of topics on the OCR specification, but the topics that can be covered are:

  • ALL of the organic functional groups and reactions
  • Organic synthesis
  • Organic analysis
  • Calculations*
  • Bonding and structure*
  • Relevant practical skills**

*Although these topics are included, they will be examined in the context of organic chemistry. So you could have a calculation to find the empirical formula of an organic compound or the percentage yield or atom economy of an organic reaction. You may also have questions related to types of bonds or bond angles within organic compound, and of course lots of questions related to intermolecular forces and the boiling points of organic compounds.

**Practical skills will focus on organic practical techniques, such as reflux, distillation, recrystallisation and purification of organic liquids.

What are the most common topics for OCR A chemistry A level Paper 2?

There are certain topics and types of question that are VERY LIKELY to come up and you should know these well, including:

  • Carboxylic acids and esters (especially condensation and hydrolysis reactions)
  • Spectroscopy
  • Testing for organic functional groups
  • Empirical formulae calculations
  • Percentage yield calculations

Predictions for OCR A chemistry A Level Paper 2 2024?

Looking through past papers, I have a few extra predictions that you should focus on for this year’s paper:

  • Alkenes and electrophilic addition reactions
  • Stereoisomerism (E/Z and optical)
  • Nucleophilic substitution (haloalkanes)
  • Nucleophilic addition (carbonyls)
  • Amides
  • Synthesis routes with benzene
  • Elimination reactions
