Interpretation: One physical property is to be named that distinguishes a molecular solid from an ionic solid.
Concept introduction:
In solids, the particles are arranged in a coordinated manner. Solids' constituent particles can only move by vibrating about a fixed axis. As a result, solids have a fixed structure and are unable to flow like liquids.
Answer to Problem 50A
Melting point
Explanation of Solution
Molecular compounds are covalent compounds and have van der Waals forces as intermolecular forces. The van der Waals forces are weak intermolecular forces and thus, have a relatively low boiling point. In ionic compounds, particles are held together by strong electrostatic forces of attraction, thus, they have a relatively high melting point.
