Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Monomers
Concept:

Polymer chemistry involves the formation of large macromolecules from smaller fundamental building blocks.

Formula:

$$N/A$$

Solution:

  • A macromolecule (or polymer) is synthesized by covalently bonding many smaller, repeating structural units together.
  • These fundamental repeating units are called monomers (from Greek mono meaning 'one' and meros meaning 'part').


Why other options are incorrect:

Metamers, isomers, and tautomers are types of molecules with the same molecular formula but different structural arrangements; they do not refer to the repeating units of a polymer.

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.
