The purpose of the experiment was to form ketones by electrophilic aromatic substitution through a Friedel-Crafts acylation reaction of an aromatic compound. In the synthesized Friedel-Craft acylation reaction mechanism, the double bond on the nucleophile anisole (methoxybenzene) attacks the acetyl electrophile. The acetyl compound is then bound to the anisole in the para position, which created the product p-methoxyacetophenone. Since anisole is an activator (electron donor), the acetyl could…
