Vedclass · Answer

(D) The reaction of sulphanilic acid with $NaNO_2$ and $CH_3COOH$ forms a diazonium salt intermediate (or a related diazo-acetate species $X$).This intermediate $X$ then undergoes an electrophilic aromatic substitution (coupling reaction) with $1$-naphthylamine.The coupling occurs at the position para to the $-NH_2$ group in the naphthylamine ring,resulting in the formation of a red azo-dye $(Y)$.The correct structure for the product $(Y)$ is shown in option $D$.

The azo-dye $(Y)$ formed in the following reactions is: $\text{Sulphanilic acid} + NaNO_2 + CH_3COOH \rightarrow X$; $X + \text{1-naphthylamine} \rightarrow Y$. Identify $Y$.
