Question

Chlorination of chlorobenzene is more difficult than that of toluene. Why?​

Answer 1

Answer:

Therefore chlorobenzene is the least reactive as chlorine is more electronegative than hydrogen meaning it is electron withdrawing so reduces the electron density of the ring making chlorobenzene the least reaction. Toluene and Phenol are more reactive than benzene since their groups add electron density to the ring.
