Vedclass · Answer

(A) The reaction of phenol with $NaOH(aq)$ forms the phenoxide ion,which is highly activated towards electrophilic aromatic substitution. $Br_2$ acts as an electrophile. The phenoxide ion undergoes electrophilic attack by $Br_2$ at the ortho and para positions. Intermediate $C$ represents the $p$-bromophenoxide ion. Intermediate $A$ represents the $o$-bromophenoxide ion. Intermediate $B$ represents a dienone intermediate formed during the bromination process. Thus,the intermediates involved in the reaction pathway are $A$,$B$,and $C$.

In the reaction of phenol with $NaOH(aq)/Br_2$,the intermediate$(s)$ is(are):
