Chlorobenzene does not undergo nucleophilic substitution

This is due to the following reason:
Resonance effect: the electron pair on chlorine atom is conjugated with pi elections of benzene ring . This results in delocalization of electrons C-Cl get partially double bond character which makes it difficult for a nucleophile to cleave the C-Cl bond.

Chlorobenzene is less reactive towards electrophilic substitution than benzene. Halogen group on benzene is a weekly deactivating group. Halogens being more electronegative than carbon, they withdraw electrons through inductive effect thereby deactivating the ring towards electrophilic substitution.
