Which of the following reactions belong to electrophilic aromatic substitution?

(A) Bromination of acetanilide

(B) Coupling reaction of aryldiazonium salts

(C) Diazotization of aniline

(D) Acylation of aniline

This is a Multiple Choice Questions as classified in NCERT Exemplar

Ans: Option (A and B)  

Benzene diazonium chloride reacts with phenol to form p-hydroxy azobenzene by coupling the phenol molecule at its para position with the diazonium salt. This is referred to as a coupling reaction. This is an illustration of an electrophilic substitution reaction. 

At room temperature, aniline reacts with bromine water to form a white precipitate of 2,4,6-tribromoaniline.

By acetylation with acetic anhydride to protect the −NH₂ group, then carrying out the desired substitution followed by hydrolysis of the substituted amide to the su
