Vedclass · Answer

(B) The reaction is an electrophilic aromatic substitution known as a coupling reaction between a phenol and a diazonium salt in an alkaline medium.In an alkaline medium,the $-OH$ group of $p$-cresol ($4$-methylphenol) is deprotonated to form a phenoxide ion $(-O^-)$.The phenoxide ion is a strongly activating group that directs the electrophile (the diazonium cation,$Ph-N_2^+$) to the ortho position relative to the $-OH$ group.Since the para position is already occupied by a methyl group $(-CH_3)$,the coupling occurs at the ortho position,resulting in $2$-phenylazo-$4$-methylphenol.
