Question

why do ionic compunds have high melting points??​

Answer 1

Answer:

High melting points in ionic compounds is due to strong electrostatic force between them. It is very hard to separate positive and negative ions in a crystal lattice.

Answer 2

ionic compound has high melting points because the electrostatic attraction needs a great deal of heat to break the energy. the ionic compound particles vibrate, with enough energy the electrostatic attraction breaks and the solid starts to melts.
