Interpretation Introduction
Interpretation: The given sets of azo dyes have to be prepared via an azo coupling reaction using the corresponding reactants which have to be identified.
Concept Introduction:
Aryldiazonium salts on coupling with an activated aromatic ring give an azo dye which produces a deep color in the final product. This color is due to the extended conjugation in it. This reaction occurs by electrophilic substitution reaction. This method is called an azo coupling. The obtained final compound is known as azo dyes.
To find: Identify the reactants involved in the given product of azo dye via an azo coupling reaction (b)
Determine the ring which is more strongly activated
