The bromination of anisole occurs without the presence of a Lewis acid catalyst and often leads to the formation of tribromide with the presence of excess bromine. Explain why.

The methoxy group withdraws electrons from the benzene ring by resonance, making the benzene ring more electrophilic.

Br₂ is a strong electrophile and readily adds to the benzene ring without using any Lewis acid catalyst.

The methoxy group donates electrons to the benzene ring by resonance, making the benzene ring more nucleophilic.

The Br–Br bond in Br₂ is weak and readily breaks to form the electrophile Br⁺.
