Vedclass · Answer

(A) The reactivity of benzene rings towards electrophilic substitution depends on the nature of the substituent attached to the ring.Electron-donating groups (activating groups) increase the electron density on the benzene ring,making it more reactive towards electrophiles.Electron-withdrawing groups (deactivating groups) decrease the electron density on the benzene ring,making it less reactive.In the given compounds:$(I)$ Toluene ($-CH_3$ group) has an electron-donating group (+$I$ and hyperconjugation effect),which activates the ring.$(II)$ Benzene has no substituent.$(III)$ Benzoic acid ($-COOH$ group) has an electron-withdrawing group (-$I$ and -$M$ effect),which deactivates the ring.Therefore,the reactivity order is: $Toluene (I) > Benzene (II) > Benzoic acid (III)$.The increasing order is $III < II < I$.

The increasing order of the following compounds for electrophilic substitution reaction is:
$(I)$ Toluene
$(II)$ Benzene
$(III)$ Benzoic acid
