Friedel Crafts Alkylation Reaction Introduction: In the experiment we will create 1‚4-Di-t-Butyl-2‚5-Dimethoxybenzene by performing a Friedel-Crafts reaction on 1‚4-Dimethoxybenzene. In the reaction a t-butyl carbocation will be added on to the 1‚4-Dimethoxybenzene. The t-butyl carbocation will be formed by a reaction of t-butyl alcohol with sulfuric acid. To perform the reaction we will create a mixture of the 1‚4-Dimethoxybenzene‚ t-butyl alcohol with acetic acid. To this mixture we will

Introduction Friedel-Crafts acylation of anisole with acetic anhydride was used in this experiement to synthesize 4-methoxyacetophenone with the use of a reflux apparatus. Friedel-Crafts reactions can be done by alkylation‚ which involves mixing an alkyl or acyl halide with a Lewis acid‚ or acylation‚ which is done with acid chlorides or anhydrides(Lefevre). Acylation was used because it does not have as many disadvantages aklyations reactions have such as polyalkylation‚ second electrophilic attacks

hyperbole‚ explosive writing‚ and symbolism to display how important the sun is to the children. Bradbury uses these three forms of craft in a very unique way.
