Question

write any four characteristics of ionic compounds . ​

Answer 1

Answer:

• They have higher enthalpies of fusion and vaporization than molecular compounds.

• They are hard.

• They are brittle.

• They have high melting points and also high boiling points

• They conduct electricity but only when they are dissolved in water.

Hope it helps you ☺️

Answer 2

The four characteristics of ionic compounds are they have crystals, hard and brittle, and so on.

Detailed answer

Ionic compounds usually have high boiling and melting point. That means we require a large amount of heat to make it boil and melt them.

• They are usually brittle but are hard so they may break if much pressure is applied to them but are hard substances.

• They are good conductors of electricity when they are made to come in contact with water.
• They are only good conductors when they come in water but otherwise, they are insulators in nature.
• High enthalpy of vapourizations.
