EAS: friedel-crafts alkylation correct answers -the friedel-crafts alkylation makes it possible for us to install an alkyl group onto an aromatic ting -this is accomplished by reacting an alkyl halide with a lewis acid to generate a species that is electrophilic enough to react with benzene -good at forming carbon-carbon bonds EAS: Friedel-Crafts alkylation-reagents correct answers -alkyl halides are generally electrophilic but no electrophilic enough to attract the benzene ring -it was fo...
