Vedclass · Answer

(C) The reactivity of benzene derivatives towards electrophilic substitution depends on the electron density of the ring.Electron-donating groups $(EDG)$ increase electron density and reactivity,while electron-withdrawing groups $(EWG)$ decrease it.- $(4)$ Phenol: The $-OH$ group is a strong activating group due to its $+M$ effect.- $(2)$ Toluene: The $-CH_3$ group is a weakly activating group due to $+I$ and hyperconjugation effects.- $(1)$ Benzene: The reference compound.- $(3)$ Chlorobenzene: The $-Cl$ group is deactivating due to its strong $-I$ effect,although it is ortho/para directing.The order of reactivity is: $	ext{Phenol} > 	ext{Toluene} > 	ext{Benzene} > 	ext{Chlorobenzene}$.Thus,the decreasing order is $(4) > (2) > (1) > (3)$.

What is the decreasing order of reactivity towards electrophilic substitution for the following compounds?
$(1)$ Benzene,$(2)$ Toluene,$(3)$ Chlorobenzene,$(4)$ Phenol
