What is the significance of acylation reactions?

Ans: Friedel–Crafts Acylation is a crucial step in the formation of many biological molecules, including DNA. Friedel Crafts’ acylation produces an acylium ion by reacting a Lewis acid, AlCl3, with an acyl halogen. Because this acylium ion is particularly electrophilic, it can be stabilised by the additional electrons from an aromatic molecule.
