Vedclass · Answer

(C) The rate of electrophilic aromatic substitution depends on the electron density of the benzene ring. Electron-donating groups (EDGs) increase the electron density and thus increase the rate of substitution.In the given compounds:- Compound $(IV)$ has two $-NH$ groups,which are strong electron-donating groups due to the resonance effect ($+R$ effect) of the lone pair on nitrogen.- Compound $(II)$ has one $-NH$ group and one $-O$ group. The $-NH$ group is a stronger electron donor than the $-O$ group.- Compound $(I)$ has two $-O$ groups,which are electron-donating but less effective than $-NH$ groups.- Compound $(III)$ has only alkyl groups,which are weak electron donors via the inductive effect ($+I$ effect).Therefore,the electron-donating ability follows the order: two $-NH$ groups $(IV)$ > one $-NH$ and one $-O$ group $(II)$ > two $-O$ groups $(I)$ > alkyl groups $(III)$.Thus,the decreasing order of the rate of electrophilic aromatic substitution is $IV > II > I > III$.

For the given compounds,what is the decreasing order of the rate of electrophilic aromatic substitution?
