Question

why do ionic compounds possess high melting and boiling point​

Answer 1

Answer:

it is a basic property of the ionic bonds or electrovelent bonds

Explanation:

There existence a strong force of attraction between the oppositely charged ions, so a large amount of energy is required to break the strong bonding force between ions.

Answer 2

Answer:

yes it is true that ionic compounds have high melting and boiling point.

Explanation:

ionic compounds have high melting and boiling point because they are bind together with electrostatic force ( cation and anion) if you can't understand this then you know that unlike charges attract each, Like Na+ and Cl-
