Concept:Molecular solids consist of discrete molecules held together by intermolecular forces (London forces, dipole-dipole, or H-bonds) when in the solid state at standard pressure and temperature conditions (or near standard for context).
Formula:Not applicable.
Solution:- Sulphur (\( \text{S}_8 \)), Phosphorus (\( \text{P}_4 \)), and Carbon dioxide (Dry ice, \( \text{CO}_2 \)) are classic examples of molecular solids.
- Bromine (\( \text{Br}_2 \)) exists as a highly volatile reddish-brown liquid at standard room temperature and pressure, not a solid.
- Therefore, under normal discussion parameters, Bromine is distinguished because its standard state is not a solid.
Why other options are incorrect:Options B, C, and D readily form molecular crystalline lattices under appropriate or standard conditions, whereas Bromine's liquid state is its defining standard characteristic.
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.
