Question

4: (A) Why do ionic compounds have high melting points?
​

Answer 1

Answer:

Ionic compounds are held together by electrostatic forces between the oppositely charged ions . ... As the ionic lattice contains such a large number of ions, a lot of energy is needed to overcome this ionic bonding so ionic compounds have high melting and boiling points.

thank you

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-
