### Step-by-Step Solution for Coupling Reaction **Step 1: Understanding Coupling Reactions** Coupling reactions typically involve diazonium salts, which are compounds containing a diazonium group (N2^+). These salts can react with various aromatic compounds to form azo compounds. **Step 2: Example of a Coupling Reaction** Consider the coupling of diazonium chloride (Ar-N2^+Cl^-) with a phenolic compound (e.g., phenol or substituted phenol). The diazonium salt acts as an electrophile in this reaction. ...
