Step 1: Understand what haloarenes are. Haloarenes are compounds that have a halogen (like chlorine, bromine, or iodine) attached to an aromatic ring (like benzene).
Step 2: Learn about nucleophilic substitution reactions. In these reactions, a nucleophile (a species that donates an electron pair) replaces a leaving group (like a halogen) in a molecule.
Step 3: Recognize that haloarenes can undergo nucleophilic substitution because the aromatic ring can stabilize the reaction.
Step 4: Conclude that the characteristic reaction of haloarenes is nucleophilic substitution due to the presence of the aromatic ring.
