Methyl (-CH3) is an Ortho, Para Directing Substituent Reactions of Aromatic Hydrocarbons Electrophilic Aromatic Substitutions (EAS) Halogenation Nitration Sulfonation Friedel-Crafts Alkylation Friedel-Crafts Acylation Effects of Substituents on Rates of Reaction Ortho, Para, and Meta Directing Substituents Slide 18: Pero some substituents direct the substitution to the meta position Trifluoromethyl (-CF3)is a Meta Directing Subtituent Slide 19: List of Substituents Based on their Effect on Orientation of Substitution and Rates of Reaction Slide 21: Practice on Ortho, Meta, Para Directing Substituents Slide 22: Practice on Ortho, Para, and Meta Directing Substituents Slide 23: Practice on Ortho, Para, and Meta Directing Substituents Slide 24: Practice on Ortho, Para, and Meta Directing Substituents Slide 25: Let’s look at the effects of a methyl and nitro substituent Reactions of Aromatic Hydrocarbons Electrophilic Aromatic Substitutions (EAS) Halogenation Nitration Sulfonation Friedel-Crafts Alkylation Friedel-Crafts Acylation Effects of Substituents on Rates of Reaction Ortho, Para, and Meta Directing Substituents Effects of Polysubstituted Aromatic Compounds Slide 26: If the directing effects of the two groups oppose each other, the more powerful activating group has the dominant influence Slide 27: Substitution rarely occurs between the two groups in a metadisubstituted compound because this site is too hindered (stearic effect) Slide 28: Practice on Ortho, Para, and Meta Directing Substituents Slide 29: Practice on Ortho, Para, and Meta Directing Substituents Slide 30: Practice on Ortho, Meta, Para Directing Substituents Slide 31: Practice on Ortho, Para, and Meta Directing Substituents Slide 32: Practice on Predicting the Product of Substitution on a Polysubstituted Benzene Slide 33: Practice on Predicting the Product of Substitution on a Polysubstituted Benzene Slide 34: Practice on Predicting the Product of Substitution on a Polysubstituted Benzene Slide 35: Reactions of Aromatic Hydrocarbons Electrophilic Aromatic Substitutions (EAS) Halogenation Nitration Sulfonation Friedel-Crafts Alkylation Friedel-Crafts Acylation Effects of Substituents on Rates of Reaction Ortho, Para, and Meta Directing Substituents Effects of Polysubstituted Aromatic Compounds You do not have the permission to view this presentation.
