Phenol

Vedclass · Answer

(C) The reactivity of an aromatic ring towards an electrophilic substitution reaction depends on the electron density of the ring. Groups that donate electrons to the ring (activating groups) increase the electron density,making the ring more susceptible to electrophilic attack. In the given compounds: $1$. Benzene: Reference compound. $2$. Chlorobenzene: $-Cl$ is a deactivating group due to its strong $-I$ effect,which outweighs its $+M$ effect. $3$. Phenol: The $-OH$ group is a strongly activating group due to its strong $+M$ effect,which significantly increases the electron density at the $o-$ and $p-$ positions. $4$. Toluene: The $-CH_3$ group is a weakly activating group due to its $+I$ effect and hyperconjugation. Therefore,phenol is the most reactive towards electrophilic attack.

Which of the following compounds will be most easily attacked by an electrophile?
