Question

Classify the following solids in different categories based on the nature of intermolecular forces operating in them: Potassium sulphate, tin, benzene, urea, ammonia, water, zinc sulphide, graphite, rubidium, argon, silicon carbide.

Answer 1

$\bf{Potassium\:sulphate}$ => Ionic solid
$\bf{Benzene}$ => Molecular solid (non-polar)
$\bf{Urea}$ => Polar molecular solid
$\bf{Ammonia}$ => Polar molecular solid
$\bf{Water}$ => Hydrogen bonded molecular solid
$\bf{Zinc\:sulphate}$ => Ionic solid
$\bf{Graphite}$ => Covalent/ Network solid
$\bf{Rubidium}$ => Metallic solid
$\bf{Argon}$ => Molecular solid (non-polar)
$\bf{Silicon Carbide}$ => Covalent/ Network solid
