Unique package of interactive PowerPoint and paper based activities that can be used for independent work or in the classroom. This resource covers A level organic aliphatic and aromatic synthetic routes through two interactive PowerPoints, each based on a clear chart of numbered synthetic routes, where each number is linked to a page detailing that reaction. Information given includes type of reaction, reagents and conditions and an equation, as well as key definitions. In addition most reactions have an animated mechanism or structural equation. There are links to pages describing and explaining practical techniques, where relevant. Includes two blank charts (one for aliphatic and one for aromatic) of the synthetic routes for printing (preferably A3 size), together with a blank table for practising types of reaction and reagents and conditions. Full answers are provided. Please review! Content covered • A level synthetic routes – aliphatic and aromatic • Extending carbon chain length (carbon-carbon bond formation) • Animated mechanisms • Key definitions • Heating under reflux • Distillation • Reaction classification • Reagents and conditions • Structural equations • Activated benzene rings • Tests for functional groups Duration: 1-3 lessons and/or independent study Please see also AS organic synthesis https://www.tes.com/teaching-resource/as-organic-synthesis-12254256
