Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Condensation
Concept:

Hydrolysis is fundamentally the reverse of condensation (also known as dehydration synthesis).

Solution:

  • In a condensation reaction, two monomers join together. A hydroxyl group (-OH) is removed from one monomer and a hydrogen atom (-H) from the other, synthesizing water and forming a covalent bond.


  • In hydrolysis, the polymer is broken down into its constituent monomers by the addition of a water molecule, which splits back into a hydroxyl group and a hydrogen atom.


Why other options are incorrect:

  • Photolysis: The breakdown of molecules caused by light.


  • Deduction/Convection: Unrelated logical and physical processes.

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.
