Doc Brown's Chemistry Advanced Level Pre-University Chemistry Revision Study Notes for UK KS5 A/AS GCE IB advanced level organic chemistry students US K12 grade 11 grade 12 organic chemistry A Level Revision Notes PART 10 Summary of organic reaction mechanisms Help in revising organic chemistry - A mechanistic introduction to organic chemistry and explanations of different types of organic reactions Part 10.4 Halogenoalkanes Elimination reactions of haloalkanes Part 10.4 HALOGENOALKANES - introduction to the mechanisms of halogenoalkanes (haloalkanes, alkyl halides). Elimination of hydrogen bromide to form alkenes [E1 and E2]. These revision notes include full diagrams and explanation of the elimination reaction mechanisms of halogenoalkanes (haloalkanes) and the 'molecular' equation and reaction conditions and other con-current reaction pathways and products are also explained when strong bases like aqueous sodium hydroxide or ethanolic potassium hydroxide react with halogenoalkanes to form alkenes.
