Question

Part A Explain why fluorobenzene is more reactive than chlorobenzene toward electrophilic aromatic substitution but chloromethylbenzene is more reactive than fluoromethylbenzene. Match the words in the left column to the appropriate blanks in the sentences on the right Reset Help nonmetal less withdraw When a halogen is attached to a benzene ring, it can donate electrons by and withdraw electrons inductively. Fluorobenzene is more reactive than chlorobenzene because fluorine is ait donating electrons by resonance. A halogen attached to a methyl group can only is Therefore, chloromethylbenzene is more reactive than fluoromethylbenzene. electrons inductively. Because fluorine resonance donate better electronegative than chlorine, it is at withdrawing electrons as well. worse more ionization halogen
