Vedclass · Answer

(A) The rate of Electrophilic Aromatic Substitution $(EAS)$ depends on the electron density of the benzene ring. Electron-donating groups $(EDG)$ activate the ring,while electron-withdrawing groups $(EWG)$ deactivate it.In structure $(C)$,the oxygen atom is directly attached to the benzene ring and acts as a strong $EDG$ through resonance,making the ring highly activated.In structure $(A)$,the oxygen atom is attached to the ring,but the carbonyl group $(C=O)$ is also present,which exerts an electron-withdrawing effect,making it less activated than $(C)$.In structure $(B)$,the carbonyl group is directly attached to the benzene ring,which is a strong $EWG$,making the ring the most deactivated among the three.Therefore,the order of increasing rate of reaction is $B < A < C$.

Rank in order of increasing rate of reaction towards $EAS$ with bromine in the presence of $FeBr_3$.
