The nitration reaction is a chemical process in which one or more nitro (NO2) groups are introduced into an aromatic nucleus by replacing a hydrogen atom. It is an electrophilic substitution reaction commonly used to modify aromatic compounds by attaching nitro groups, which can significantly alter their properties and reactivity.

The Friedel-Crafts acylation involves the production of an aromatic ketone by the reaction between an aromatic compound and an acylating agent, which could be an acyl halide, an acid anhydride, an acid, or an ester. This reaction takes place in the presence of an acidic catalyst.

The Friedel-Crafts alkylation of aromatic compounds involves an acid-catalyzed electrophilic substitution, wherein an alkyl group replaces an aromatic hydrogen. A diverse range of alkylating agents, such as olefins, alkyl halides, and alcohols, is commonly employed for this purpose.
