in chlorobenzene the electron pair of chlorine atom is in conjugation with the pi electron of benzene ring . thus chlorobenzene is a resonance hybrid , 
the C-CL bond have partial double bond charecter , as a result the c-cl bond in chlorobenzene is shorter and hence stronger , 
thus cleavage of c-cl bond in benzene becomes difficult , which makes it less reactive . 
HOPE IT CLEARS 
ALL THE BEST
