Benzene Fluorination and Iodination Reactions

Benzene fluorination and iodination are examples of electrophilic aromatic substitution. These reactions add a halogen to an aromatic ring, but they are harder to carry out than bromination or chlorination. The video focuses on why fluorine and iodine behave differently in these substitutions.

Bromination and chlorination of aromatic rings by electrophilic substitution reactions are easily achieved. However, fluorination and iodination are exceptional.

Among all halogens, fluorine is highly reactive towards aromatic rings. Therefore, it is difficult to limit the direct fluorination of benzene, resulting in poor yields of monofl...
