Friedel-Crafts Discussion and Conclusion In this lab experiment, Friedel-Crafts acylation was carried out using an unknown hydrocarbon starting material. In order to carry out the reaction, new techniques were employed, such as, handling highly reactive chemicals, controlling the formation of hydrogen chloride gas and the use of reduced pressure distillation. NMR spectroscopy was used in order to decipher the product, which then allows you to work out what the starting material is. Friedel-Crafts acylation and alkylation are useful reactions because they involve carbon-carbon bond formation, as well as, the substitution of acyl and alkyl groups onto aromatic rings. In our particular reaction, acylation is being carried out opposed to alkylation. To substitute an alkyl group onto a ring, the reaction would require the use of a strong lewis acid and an alkyl group attached to a halogen. Because only the alkyl group is being substituted, some disadvantages exist; rearrangement can occur (1,2-
