Ethers can again be classified into two varieties.
In organic chemistry an aryl halide also known as haloarene or halogenoarene is an aromatic compound in which one or more hydrogen atoms directly bonded to an aromatic ring are replaced by a halide the haloarene are different from haloalkanes because they exhibit many differences in methods of preparation and properties.
