Arenediazoniums can undergo electrophilic aromatic substitutions with a wide variety of activated aromatic compounds to yield new azo dyes. This chemistry is also seen in the Sandmeyer reaction. Consider the reaction sequence below, which forms an arenediazonium in situ using p-nitroaniline as one of the starting materials, and answer the questions that follow. The second aromatic reactant has one of three possible R-groups: \( \mathrm{OMe}, \mathrm{OH} \), or \( \mathrm{COOH} \). Using the following IR spectrum of this unknown reactant, draw the correct structure. Reprinted by permission. SDBSWeb : https.u/sdbs db aist go jp.
