This is a detailed 172 page powerpoint resource I made for myself during my A-levels that helped me get an A*. I added to it at the end of each lesson/topic, cross-referencing between my notes, the textbook, revision guides and most importantly each point of the specification ; I also updated it with any details from marks I’d missed on tests. Great to go through to better understand topics, as print-outs for revision posters or to review entire modules for the exams or mocks. It covers all topics for the NEW A-level OCR specification detailed below and at http://www.ocr.org.uk/Images/171720-specification-accredited-a-level-gce-chemistry-a-h432.pdf • Knowledge of the required practicals and practical skills • Atoms, compounds, molecules and equations Amount of substance • Acid–base and redox reactions • Electrons, bonding and structure • The periodic table and periodicity • Group 2 and the halogens • Qualitative analysis • Enthalpy changes • Reaction rates and equilibrium (qualitative) • Basic concepts • Hydrocarbons • Alcohols and haloalkanes • Organic synthesis • Analytical techniques (IR and MS) • Reaction rates and equilibrium (quantitative) • pH and buffers • Enthalpy, entropy and free energy • Redox and electrode potentials • Transition elements • Aromatic compounds • Carbonyl compounds • Carboxylic acids and esters • Nitrogen compounds Polymers • Organic synthesis • Chromatography and spectroscopy (NMR)
