WebAromatic rings can be brominated using Br 2 in the presence of FeBr 3. The electrophile is Br +. Friedal-Crafts acylation reaction occurs when an aromatic compound is treated with an acyl chloride in the presence of AlCl 3. The electrophile is RCO +. WebBromination is a chemical reaction involving the reaction of a compound, and bromine results in bromine being added to the compound. A saturated compound undergoes bromination via a free radical mechanism. In contrast, unsaturated and aromatic compounds undergo bromination via addition and electrophilic substitution mechanism.
