Question

Write the chemical reaction of coupling reaction \(\underline{\hspace{2cm}}\)

Hint:

Coupling reactions are commonly used in azo dye synthesis.

Answer 1

Step 1: Coupling reaction.
Coupling reactions involve the reaction of two aromatic compounds, often involving a diazonium ion as an intermediate. An example is the formation of \( p \)-hydroxy azobenzene from an aromatic amine and a diazonium salt.

Step 2: Conclusion.
An example of a coupling reaction produces \( p \)-hydroxy azobenzene.
