Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Crystal energy
Concept:
Lattice energy represents the energy released when gaseous ions bind to form an ionic solid, or the energy required to break the solid into gaseous ions.

Solution:
  • Because this energy is fundamentally tied to the formation and stability of the crystal lattice structure itself, it is synonymously referred to as crystal energy.


Why other options are incorrect:
  • A, B, D: Electron affinity relates to gaining electrons, bond energy usually refers to covalent bonds between atoms in a molecule, and potential energy is a general physics term, not specifically synonymous with lattice energy.

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.
