Chlorobenzene is less reactive towards nucleophillic substitution due to –
1. resonance , C- Cl bond acquires a partial double bond character and becomes stronger than a single bond.
2. sp2 hybridisation in C of C-X bond, the carbon becomes more electronegative and holds the electron pair of C-X bond more tightly decreasing the bond length
