Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: KOCN
Concept:

Organic compounds are fundamentally carbon-based, usually possessing C-C and C-H bonds. Certain simple carbon compounds (carbonates, cyanates, carbides, oxides) are classified historically and chemically as inorganic salts.

Solution:

  • B: Phenol (\( \text{C}_6\text{H}_5\text{OH} \)) is an aromatic organic compound.


  • C: Acetone (\( \text{CH}_3\text{COCH}_3 \)) is an organic ketone.


  • D: Methanol (\( \text{CH}_3\text{OH} \)) is an organic alcohol.


  • A: Potassium cyanate (KOCN) is an ionic salt. Despite containing carbon, cyanates are universally studied under inorganic chemistry.


Why other options are incorrect:

Options B, C, and D are classical, covalent organic molecules.

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.
