Chemistry AS OCR/B/Salters New Specification

Length of course: 5 half-day sessions
Boards: OCR/B H033 Salters only

This course is board-specific for the NEW OCR/B/Salters AS level specification (H033).

This course is for AS students only.

This course is not suitable for students re-sitting units from the outgoing Chemistry AS OCR/B/Salters (H035) specification.

The following topics (storylines) will be covered:

  • Elements of life - atomic structure, atomic spectra and electron configurations; fusion reactions; mass spectrometry and isotopes; the periodic table and Group 2 chemistry; bonding and the shapes of molecules; chemical equations and amount of substance (moles); ions: formulae, charge density, tests; titrations and titration calculations.
  • Developing fuels - the chemical ideas in this module are: thermochemistry; organic chemistry: names and combustion of alkanes, alkenes, alcohols; heterogeneous catalysis; reactions of alkenes; addition polymers; electrophilic addition; gas volume calculations; shapes of organic molecules, σ- and π-bonds; structural and E/Z isomers; dealing with polluting gases.
  • Elements from the sea - halogen chemistry; redox chemistry and electrolysis; equilibrium; atom economy.
  • The ozone story - composition by volume of gases; the electromagnetic spectrum and the interaction of radiation with matter; rates of reaction; radical reactions; intermolecular bonding; haloalkanes; nucleophilic substitution reactions; the sustainability of the ozone layer.
  • What’s in a medicine? - the chemistry of the –OH group, phenols and alcohols; carboxylic acids and esters; mass spectrometry and IR spectroscopy; organic synthesis, preparative techniques and thin layer chromatography; green chemistry.

Where appropriate, help will also be provided for practical skills assessed in a written examination.
