Official Correct Choice:
Option D: Formaldehyde & phenol
Concept:

Bakelite is a heavily cross-linked thermosetting plastic formed by a condensation polymerization reaction.

Formula:

Not applicable to this conceptual question.

Solution:

  • The monomers used to create Bakelite are phenol and formaldehyde.


  • They react to form ortho- and para-hydroxybenzyl alcohols, which then undergo condensation (losing water) to form complex methylene bridges between the phenol rings, creating the solid 3D polymer structure.


Why other options are incorrect:

Glucose makes cellulose or starch. Amino acids make proteins/polyamides. Acetone is not used in Bakelite synthesis.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
