Extensively and thoroughly organised list of all organic reactions required in the latest CIE A2 Chemistry syllabus. A must-have revision tool that helped me gain an A* in Chemistry in the final A Levels massively.
⏣ -25–60oC
-refluxed
H+ + HSO4- → H2SO4
-excess nitration → NO2
at position 3/5
-at >60oC w/ ⏣CH3 →
NO2 at positions 2,4,6
-steamy white fumes
-electrophile formed by:
CH3Cl + AlCl3 → CH2+ +
