Classify the following solids in different categories based on the nature of intermolecular forces operating in them:

Solution:

Substance                            Type of solid

Potassium sulphate           Ionic solid

Benzene                               Molecular solid (non-polar)

Urea                                      Polar molecular solid

Ammonia                             Polar molecular solid

Water                                   Hydrogen bonded molecular solid

Zinc sulphate                      Ionic solid 

Graphite                              Covalent/ Network solid

Rubidium                             Metallic solid

Argon                                    Molecular solid (non-polar)

Silicon Carbide                    Covalent/ Network solid

Explanation: Ionic solids are those in which constituents particles are cations and anions which are held together by columbic force of interactions 

e.g.- K2SO4 ⇒ K+  +  SO4—

Metallic solids are metals in which metal ions (also called kernals) are held together by metallic bonds.)

Molecular solids are made up on molecules or inert gases.

In covalent solids constituent particles are atoms which are held together by continuous system of covalent bonds.

Note: Though in solid argon the constituent particles are atoms even it is categorised as molecular solid because the particles are held together by vander waal forces so all solids of zero group elements are placed under the category of molecular solids.)
