AQA Organic chemistry flash cards
polarity24polarity24

AQA Organic chemistry flash cards

(1)
A set of 128 printable flash cards suitable for the AQA A-Level Chemistry topic of Organic chemistry. Questions cover theory on the naming, sketching of displayed, structural and skeletal formulae, fractional distillation, cracking, reforming, oxidation, combustion, hydrogenation, electrophilic addition, inductive effect, polymerisation etc. Covers all the informtion they need to know about introductory chemistry on the alkanes and alkenes including the mechanisms of free radical substitution and electrophilic additon (markovnikov). In PowerPoint format, the cue cards print out in the correct format. Once printed, all it takes 1 minute to slice the cards and prepare a set, is formatted so the answers will show on the reverse of the question card.
