d.  These compounds are brittle and break into small pieces easily.

                    Reason- Due to their crystalline structure.


                e.  Electrovalent compounds usually dissolve in water and are insoluble in solvents
                    like oil, petrol, kerosene, etc.

                    Reason- As water is a polar solvent and ionic compounds also carry charges,
                    they readily dissolve in water.




























                f.  Ionic compounds do not conduct electricity in a solid-state but they do conduct
                    electricity in the molten state.


                    Reason- The charged particles i.e. Ions are mobile in their aqueous medium.
                    So they conduct electricity.




























                       The charged particles i.e. Ions are mobile in their aqueous medium. So they
               conduct electricity.
