Chapter 16, Problem 115AE

Interpretation Introduction

Interpretation: Whether the given substance is ionic, network, metallic or molecular solids needs to be determined.

  ${\text{B}}_{\text{2}}{\text{H}}_{\text{6}}{\text{, SiO}}_{\text{2}}\text{, CsI, W}$

Concept Introduction:

Solid state has strong intermolecular force of attraction between particles whereas the gaseous particles have weakest intermolecular forces between particles. Due to intermolecular force of attraction between particles, different interconversions are possible between these three states like evaporation, condensation, sublimation etc.

On the basis of structure and intermolecular interactions, solids can further classified as:

• Crystalline solids - Molecular solids, network solid, ionic solids, metallic solids
• Amorphous solid
