In both alkyl halides and aryl halides, the halogen (X) atom is attached directly to the carbon atom. They are expected to exhibit similar reactivity. However, aryl halides are comparatively very little reactive, particularly towards nucleophilic substitution reaction. for example, hydrolysis of ethyl chloride occurs by simply boiling with aqueous KOH. ON the other hand, the alkaline hydrolysis of chlorobenzene requires a very high temperature (623K) as well as a very high pressure.

B. Benzyl chloride

D. Benzene hexachloride.
