Question

For diazonium ions, the order of reactivity towards diazonium coupling with phenol in the presence of dil. NaOH is

• A. I < IV < II < III
• B. III < IV < II < I
• C. I < II < IV < III
• D. IV < II < I < III

Answer 1

The correct option is D IV < II < I < III

Presence of electron with drawing group in arene diazonium ions enhances the electro phillic character of the ions and thus increases coupling.
