Revising Advanced Organic Chemistry Doc Brown's GCE Chemistry
Revision Notes PART 10 Summary of organic reaction mechanisms - A mechanistic introduction to organic chemistry and explanations of different types of organic reactions
Part 10.8 Aromatic Hydrocarbons - Arenes - Electrophilic substitution reactions - CHLORINATION & BROMINATION
Part 10.8 AROMATIC HYDROCARBONS (ARENES) - introduction to arene electrophilic substitutions. Chlorination/bromination to aromatics like chlorobenzene, bromobenzene etc. The orientation of products in aromatic substitution (1,2-; 1,3-; and 1,4- positions for two substituents in the benzene ring, old names - ortho/meta/para substitution products). The revision notes include full diagrams and explanation of the mechanisms and the 'molecular' equation and reaction conditions and other con-current reaction pathways and products are also explained for the reaction mechanisms of aromatic hydrocarbons like benzene and methylbenzene.
Part 10.8 AROMATIC HYDROCARBONS (Arenes)
10.8.1 Introduction to the reactivity of aromatic compounds
e.g. the arenes benzene and methyl benzene
Why do aromatic hydrocarbon molecules primarily react via electrophilic substitution reaction?
10.8.3 The electrophilic substitution of an arene - chlorination mechanism (example of aromatic halogenation)
Organic synthesis of chloro/bromo aromatic compounds by reaction of chlorine/bromine with benzene/methylbenzene
mechanism 21 - electrophilic substitution by halogen in a benzene ring
10.8.7 The orientation of products in aromatic electrophilic substitution reactions
keywords phrases: reaction conditions formula intermediates organic chemistry reaction mechanisms electrophilic substitution methylbenzene benzene C6H6 + Cl2 ==> C6H5Cl + HCl initiation: free radical substitution chlorination chain propagations: Cl. + C6H5CH3 ==> HCl + C6H5CH2
