Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: 0.88 g/cm³
Concept:

Physical properties of aromatic hydrocarbons include their state, color, and density relative to water.

Solution:

  • Benzene is a colorless, highly flammable liquid with a sweet odor.


  • Like most hydrocarbons, it is less dense than water (which has a density of 1.00 g/cm³).


  • The experimentally determined density of pure liquid benzene at room temperature is approximately 0.876 g/cm³, which is standardly rounded to 0.88 g/cm³ in chemical literature.


Why other options are incorrect:

  • 0.80, 0.85, and 0.08 are factually incorrect values for the specific gravity/density of benzene.

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.
