Diazotisation followed by coupling with phenol

Vedclass · Answer

(B) The correct answer is $B$. Aniline undergoes diazotisation with $HNO_2$ at $0-5 \ ^{\circ}C$ to form benzene diazonium chloride,which then couples with phenol to form an azo dye (a yellow-orange precipitate). Methyl amine $(CH_3NH_2)$ does not form a stable diazonium salt under these conditions and does not undergo the coupling reaction with phenol.
