Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Oxidizing agent
Concept:

The -OH group on the phenol ring strongly donates electrons, making the aromatic ring extremely electron-rich.

Formula:

Not applicable to this conceptual question.

Solution:

  • Because phenols are highly electron-rich, they are very susceptible to losing electrons.


  • Therefore, they are extremely reactive toward oxidizing agents (which accept electrons). Exposure to air or mild oxidants easily converts them into quinones.


Why other options are incorrect:

Electron-rich rings resist reducing agents (which want to give them more electrons). Phenols do not easily undergo dehydration like aliphatic alcohols do.

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.
