Concept:A haloarene is an aromatic compound in which a halogen atom is directly attached to the benzene ring.
Explanation:Haloarenes are also called aryl halides.
Their general formula is
Ar−X, where
X is a halogen atom.
In a haloarene, the halogen is directly bonded to the
sp2 hybridised carbon atom of the aromatic ring.
This direct bonding to the aromatic ring is the main identifying feature of haloarenes.
To find the correct option, examine each structure and locate the one in which the halogen is joined directly to the benzene ring.
If the halogen is attached to a side chain, the compound is not a haloarene.
Thus, the structure with the halogen directly on the aromatic ring is the correct haloarene.
Answer:The correct option is the one in which the halogen atom is directly bonded to the
sp2 hybridised carbon atom of the aromatic ring.
