Question

what are the properties of ionic compound ?​

Answer 1

Iconic compounds also exhibit the following properties:

• They form crystals.
• Ionic compounds form crystal lattices rather than amorphous solids. Although molecular compounds form crystals, they frequently take other forms plus molecular crystals typically are softer than ionic crystals. At an atomic level, an ionic crystal is a regular structure, with the cation and anion alternating with each other and forming a three-dimensional structure based largely on the smaller ion evenly filling in the gaps between the larger ion.
• They have high melting points and high boiling points.High temperatures are required to overcome the attraction between the positive and negative ions in ionic compounds. Therefore, a lot of energy is required to melt ionic compounds or cause them to boil.
• They have higher enthalpies of fusion and vaporization than molecular compounds.

Answer 2

Answer:

Ionic compounds have high melting and boiling points because a application of significant amount of energy can break the strong inter-ionic attraction .Ionic compounds are soluble in water but insoluble in solvents like kerosene,petrol.
