Question of the day

What will be the reactivity of chlorobenzene in an electrophilic substitution reaction with benzene?

The rate of the reaction depends on the electron density in the ring and here in this case resonance is not favorable and the electronegativity dipole dominates. This slows down the reactivity of chlorobenzene.

Reacts very slowly compare to benzene Reacts in the same way as benzene Reacts faster than benzene Does not react with benzene Cannot determine
