Question

The functionality of the Phenol in the preparation of phenol-formaldehyde resin is :

• A. 1
• B. 2
• C. 3
• D. 4

Hint:

In phenol-formaldehyde resin synthesis, phenol's reactivity and functionality define the resin's final properties.

Answer 1

The Correct Option is D

Step 1: Role of Phenol. Phenol is essential for synthesizing phenol-formaldehyde resin, participating in the reaction with formaldehyde to create the polymer.

Step 2: Conclusion. The reactivity of phenol, considering its chemical properties and the reaction mechanism, indicates a functionality of (D) 4 in this preparation.
