Question

why do ionic compounds have high melting points?​

Answer 1

$\purple{\text{Answer }}$

Explanation:

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.

Answer 2

: Required Answer

$\longrightarrow$ Ionic compounds are the ones which has both positive and negative charges. Hence there will be strong force of attraction between them. This make expenditure of lot of heat to break this force of attraction hence ionic compounds have high melting points.
