Question

why do ionic compounds have high melting ​

Answer 1

Explanation:

onic 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.

Answer 2

Answer:

Because, ionic compounds have strong bonding nature.

Their bond is strong. SO,  melting and boiling points are very high
