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

Craft Moves Essay Ray Bradbury focused on multiple craft moves‚ similes‚ descriptive words‚ and foreshadowing to give readers a painted picture in their mind while reading and to also be able to predict what will happen in the end. The first craft move Bradbury uses is foreshadowing . In the story Bradbury uses foreshadowing by hinting out through the whole story that the parents get eaten before it happens. For example “You see‚ there are the lions‚ far over‚ that way. Now they’re on their way

Jessica Zebracki Organic Chem II Lab 2/15/15 Friedel-Crafts Acylation of Ferrocene and Column Chromatography Introduction: The intention of this lab is to analyze the formation of acetylferrocene using column chromatography. The Friedel-Crafts acylation reaction created acetylferrocene and diacetylferrocene‚ using phosphoric acid as a catalyst for the reaction between acetic anhydride and ferrocene (once applying heat). During column chromatography‚ a solution is passed through a filtration system

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. His use of simile and metaphor can also be argued to be forms of craft the author uses to send his message across. Overstatement‚ symbolism‚ and extremely detailed writing are all different styles of author’s craft. But all three are being used to emphasize the same purpose from the story. All Summer In A Day‚ by Ray Bradbury uses symbolism‚
