You might have to rephrase this question, because I am not seeing from where you are coming.

Explanation:

You know that the benzene ring, #C_6H_6#, is aromatically stabilized. The six #pi# electrons are delocalized around the carbocyclic ring, and effect energetic stabilization of the ring with respect to an hypothetical #"1,3,5-cyclohexatriene"#.

Substitute the ring, i.e. #C_6H_5X#, and even given the carbon-heteroatom bond, aromatic stability is retained.
