Aryl halides are less reactive as compared to alkyl halides as the halogen atom in these compounds is directly attached with benzene ring and cannot be replaced by nucleophiles such as , , etc. In chlorobenzene, the electron pair of chlorine atom is in conjugation with -electrons of benzene ring. Thus C - Cl bond acquires partial double bond character and is difficult to break.
