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...

silicates - minerals that contain silicon and oxygen and usually one or more other elements, are one of the largest groups of minerals oxides - compounds that have oxygen as their anion, t ut they exclude those with oxygen complexes such as carbonate, suphate, and silicate. have O2 as their anion, Ways rocks may form - Igneous: forms from magma that has either cooled slowly under ground or cooled quickly at the surface after a volcanic eruption Sedimentary rocks: formed when weathered frag...
