Question
The functionality of a monomer dictates the topology of the resulting polymer. In the formation of the 3D infusible network of Bakelite, what is the effective functionality of phenol?
Answer: C
💡 Solution & Explanation
The highly activating $-OH$ group makes phenol susceptible to electrophilic attack by formaldehyde at two *ortho* positions and one *para* position. This grants it a functionality of 3, essential for forming full 3D cross-links.
