2. Draw the structure of the byproduct that would be formed if the reaction mixture were not kept in an ice bath during the azo coupling reaction. [2 pts) Methyl orange can be synthesized using an azo coupling reaction, which is an example of an electrophilic aromatic substitution (EAS). In an azo coupling, the electrophile is an aryldiazonium salt, and the nucleophile is another electron-rich aromatic compound (typically an aniline or phenol). In this experiment, sulfanilic acid will be converted...
