Vedclass · Accepted Answer

$Anisole$

Vedclass · Answer

(A) The reactivity toward electrophilic aromatic substitution is determined by the electron density on the benzene ring. Groups that donate electrons to the ring increase its electron density,making it more reactive toward electrophiles. $Anisole$ $(C_6H_5OCH_3)$ contains a methoxy group $(-OCH_3)$,which is a strong electron-donating group due to the resonance effect ($+R$ effect). $Benzene$ has no substituent. $Nitrobenzene$ $(C_6H_5NO_2)$ contains a nitro group $(-NO_2)$,which is a strong electron-withdrawing group ($-I$ and $-R$ effects). $Chlorobenzene$ $(C_6H_5Cl)$ contains a chlorine atom,which is deactivating due to its strong inductive effect ($-I$ effect) despite its resonance donation ($+R$ effect). Therefore,$Anisole$ is the most reactive among the given options.
