Which of the following undergoes the most rapid bromination upon treatment with Br₂/FeBr₃? A) benzene B) nitrobenzene C) bromobenzene D) anisole

Question

Quizplus · Accepted Answer

Anisole undergoes the most rapid bromination upon treatment with Br2/FeBr3 due to the electron-donating methoxy group (-OCH3) which activates the benzene ring towards electrophilic aromatic substitution, making it more reactive towards bromination compared to benzene, nitrobenzene (which is deactivated by the electron-withdrawing nitro group), and bromobenzene (where the bromine is slightly deactivating due to its electronegativity despite being an ortho/para director).
