Question

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.

Chemical reaction showing bromination of anisole to form tribromide with excess Br2.

Accepted Answer

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

Answer

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

Answer

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

Answer

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