Chlorobenzene is more reactive towards electrophilic aromatic substitution than bromobenzene. However, (bromomethyl)benzene is more reactive than (chloromethyl)benzene. Rationalize this observation.

Chlorine is more electronegative than bromine, making chlorobenzene more reactive, while chlorine is a better electron donor by resonance, making (bromomethyl)benzene more reactive.

Chlorine is a better electron donor by resonance, making chlorobenzene more reactive, while chlorine is more electronegative than bromine and withdraws electrons better, making (bromomethyl)benzene more reactive.

Bromine is more electronegative than chlorine, making chlorobenzene more reactive, while chlorine is a better resonance donor, making (bromomethyl)benzene more reactive.

Bromine is a better electron donor by resonance, making chlorobenzene more reactive, while bromine is more electronegative than chlorine bromine and withdraws electrons better, making (bromomethyl)benzene more reactive.
