Solution

The correct options are
B High melting points and non-directional bonds
C High solubilities in polar solvents
D Good conductors of electricity in molten state
Ionic compounds are formed due to the strong electrostatic forces of attraction between cations and anions.

They exist as a three-dimensional lattice structure in solid-state. Due to this, ionic compounds have high boiling and melting points.

They dissolve readily in polar solvents e.g. water (water being polar in water) but are insoluble in non-polar solvents. This is so because solubility follows the principle- like dissolves like.

They are good conductors of electricity in a molten state as they are made up of ions.
